For example, when we look at \u00be, when we think of it as a part of a whole, we can imagine it representing 3 slices of a pizza that is split into four parts. We can now take this fraction and apply it to multiple different pizzas. Say that there is already a pizza but half of it has already been eaten. Since you love practicing fractions and eating pizza, you want to eat only \u00be of this half-eaten pizza. All we have to do in this case is multiply \u00be by \u00bd to get \u215c, and with this product, we now know that we have to cut the remainder of this pizza into 8 slices and eat three of those slices.\u00a0<\/p>\r\n\r\n\r\n\r\n<p>For the ACT math section, be sure to know how to:<\/p>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list\">\r\n<li>Simplify fractions<\/li>\r\n<li>Convert back and forth between mixed numbers and improper fractions (ex. 3 \u2153 to 10\/3)<\/li>\r\n<li>Add, subtract, multiply, and divide fractions<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Decimals<\/h3>\r\n\r\n\r\n\r\n<p>Decimals are numbers that fall between integers and are described as digits following a decimal point. We can describe these parts based on units of tens (tenths, hundredths, thousandths, and on) and use them to convert back to fractions! We can convert 0.1 to a fraction by dividing 1 by 10, 0.01 by dividing 1 by 100, and so on. If we have something like 1.01, we can convert to a fraction by writing out the mixed number and going to an improper fraction if needed: so 1 and 1\/100ths will thus simplify to 101\/100. Going from fractions to decimals, on the other hand, is much simpler. Simply divide the numerator by the denominator and you have your decimal!<\/p>\r\n\r\n\r\n\r\n<p>For the ACT math section, be sure to know how to:<\/p>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list\">\r\n<li>Convert from a decimal to a fraction and vice versa<\/li>\r\n<li>Add, subtract, multiply, and divide decimals<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<h4 class=\"has-text-align-center wp-block-heading\"><a href=\"https:\/\/www.testgeek.com\/online-sat-tutoring-online-act-tutoring.html?utm_source=blog&amp;utm_medium=blog&amp;utm_campaign=blog_highlight\" target=\"_blank\" rel=\"noreferrer noopener\">Feeling Overwhelmed?

Because decimals represent fractions just in a different format, the same process goes for them! If we want to convert 0.3 to a percentage, simply multiply by 100% to get us 30%.\u00a0<\/p>\r\n\r\n\r\n\r\n<p>To go from percentages to decimals and fractions, we simply do the opposite of multiplying by 100: dividing by 100! Let\u2019s convert 15%: 15\/100 simplifies to 3\/20, giving us our simplified fraction, and simplifying it to a decimal gives us 0.15!\u00a0<\/p>\r\n\r\n\r\n\r\n<p>For the ACT math section, be sure to know how to:<\/p>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list\">\r\n<li>Convert between percentages, decimals, and fractions<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"848\" height=\"566\" class=\"wp-image-4232\" src=\"https:\/\/www.testgeek.com\/blog\/wp-content\/uploads\/2022\/02\/fifth-grader.jpg\" alt=\"\" srcset=\"https:\/\/www.testgeek.com\/blog\/wp-content\/uploads\/2022\/02\/fifth-grader.jpg 848w, https:\/\/www.testgeek.com\/blog\/wp-content\/uploads\/2022\/02\/fifth-grader-300x200.jpg 300w, https:\/\/www.testgeek.com\/blog\/wp-content\/uploads\/2022\/02\/fifth-grader-768x513.jpg 768w, https:\/\/www.testgeek.com\/blog\/wp-content\/uploads\/2022\/02\/fifth-grader-800x534.jpg 800w\" sizes=\"(max-width: 848px) 100vw, 848px\" \/>\r\n<figcaption>Silly mistakes are real!

Like I mentioned earlier, the difficulty mostly comes with setting up the calculation, not the actual calculation (silly mistakes, on the other hand, are a different topic). So in order to set up an accurate problem, we must understand the problem completely. For these next few practice problems, we\u2019ll be following three main steps.<\/p>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list\">\r\n<li><strong>Understand the context of the math.<\/strong><\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<p>This is undoubtedly the hardest part, but if you genuinely understand the context of the arithmetic you\u2019re doing, the algebra won\u2019t fail! Read through the question and identify what operations you\u2019ll need, and don\u2019t be afraid to work with some test numbers.<\/p>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list\" start=\"2\">\r\n<li><strong>Generalize a solution<\/strong>.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<p>After developing context, you should have a general gist of the steps you\u2019ll need to do. For example, what will go on both sides of the equation? What are the steps in finding x percent of this? You\u2019ll be asking a general question, but you\u2019ll also be providing a general question.<\/p>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list\" start=\"3\">\r\n<li><strong>Apply the general solution<\/strong>.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<p>With your general outline, go into the problem and apply the numbers!<\/p>\r\n\r\n\r\n\r\n<p>The steps sound pretty broad, so let\u2019s get into some practice. To begin, let\u2019s actually go back to Sally and her long jump from earlier.<\/p>\r\n\r\n\r\n\r\n<p>&nbsp;<\/p>\r\n\r\n\r\n\r\n<p><strong style=\"font-style: italic;\">In 1991, Sally improved her long jump distance by 10%.

Now, what does this mean mathematically? When we increase a number by 10% of it, we basically find 10% of that number and then add it on to what we had before. For example, if we increase 10 by 10%, we see that 10% of 10 is 1 (aka 0.1*10), so increasing it by 1 is simply 10+1, or 11.\u00a0<\/p>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list\" start=\"2\">\r\n<li>Generalize a solution<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<p>From our context above, we can think of increasing a number by 10% as multiplying that number by 1.1: in other words, we keep the whole number and add 10% of it, thus the 1 and 0.1 portion. We can generalize an increase by x% as multiplying that number by 1+(x\/100).\u00a0<\/p>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list\" start=\"3\">\r\n<li>Apply the general solution<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<p>Now that we know how to increase a number by x%, let\u2019s work through the entire problem.<\/p>\r\n\r\n\r\n\r\n<p>The problem never specified her initial distance, so let\u2019s call it &#8220;d.&#8221; An increase in 10% means multiplying d by 1.1, so in 1991, her distance is 1.1d. In 1992, she then improved her PREVIOUS year by 20%, so we know that we are going to multiply the previous year by 1.2 (remember, 1+ 20\/100 is 1 + 2\/10).\u00a0When we multiply 1.2(1.1d), we get a product of 1.32d.<\/p>\r\n\r\n\r\n\r\n<p>Okay, so if we know that 1.1d represents a 10% increase in d, we know that 1.32d represents a 32% increase.

How do we find common denominators? Common multiples! When adding \u00bd and \u2153, we can find the common denominator by multiplying 2 and 3 together, so in this case, we can find our common denominator doing the same thing. We\u2019ll have to make sure to adjust the numerators to keep the original value the same, and then we\u2019ll add.<\/p>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list\" start=\"3\">\r\n<li>Apply the general solution.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n<p>Our common denominator will be 8x, so let\u2019s start by simplifying the first fraction. How do we go from 8 to 8x? We multiply by x, so this means that in order to keep the proportions the same, we\u2019ll also have to multiply the numerator by x. After all, 7x\/8x simplifies to \u215e again. With the second fraction, we have to multiply x by 8 to get to 8x, so this means we also multiply the numerator by 8. In doing so, we know have 80\/8x, which we know simplifies back down to 10\/x.\u00a0<\/p>\r\n\r\n\r\n\r\n<p>We have our simplified fractions, 7x\/8x and 80\/8x, so let\u2019s add!
