Tips for Comparing Fractions - Comparing fractions is one of the few struggles of students in grades 1, 2, 3 and 4. However, there are a few essential tips and tricks that make this a lot easier what most students might think. When two fractions are in place, there a few tricks that can help you compare them with each other. This trick can help you identify which one is the bigger one. For example, let's compare 3/8 with 4/9. You multiply the numerator of the first fractions by the denominator of the second fraction. Now compare the answers of the two. 3 x 9 = 27 4 x 8 = 32 Since 32 is the larger number than 27, we know that 4/9 is a far greater number than 3/8. You need to make sure that your answer related to the numerator. So, in this example, 27 was related to 3/8, and 32 was related to 4/9. Hence, between the two fractions, 4/9 is greater. 74. How to Recognize Equivalent Fractions In mathematics, equivalent fractions are fractions with the same value, but they don't look similar. More accurately, they are defined as integers with different numerators and denominators that represent the same proportion. Equivalent fractions, when expressed on a number line, represent the same points or distance on it. They produce the same result when reduced to their simplest forms. To recognize equivalent fractions, you must know these two tricks. Consider this example: ½ = 2/4 = 4/8 These fractions are equivalent; however, they use different numbers. But how do you find that out? The first rule to recognizing an equivalent fraction is to multiply or divide both the numerator and denominator by the same number. If multiplying 1(numerator) and 2 (denominator) of ½ gives the fraction 2/4, then these fractions are equivalent. 1x2 / 2x2 = 2/4 Another trick is to cross multiply the fractions to find out if they are equivalent or not. Now here, cross-multiplying refers to multiplying one's numerator with the other's denominator. 2 x 8 = 4 x 4 = 16 The fractions are equivalent.
