Arrow-Puffin-4_Semester-1 Maths 191Checking Equivalent FractionsLet's Understand Conceptual UnderstandingTo check if the given fractions are equivalent, multiply the numerator of the first fraction with the denominator of the second fraction and multiply the denominator of the first fraction with the numerator of the second fraction.This method of multiplication is called cross multiplication.Example 1 : Are the fractions 812 and 23 equivalent?Cross multiply the fractions 812 and 23 .8 x 3 = 2412 x 2 = 24The products after the cross multiplication are the same.Therefore, 812 and 23 are equivalent fractions.Example 2 : Are the fractions 2149 and 37 equivalent?Cross multiply the fractions 21 49 and 37 .21 x 7 = 14749 x 3 = 147The products after the cross multiplication are the same.Therefore, 2149 and 37 are equivalent fractions.Example 1 : 416 = 4 %u00f7 416 %u00f7 4 = 14 416 and 14 are equivalent fractions.Example 2 :23 = 2 x 33 x 3 = 69 23 and 69 are equivalent fractions.
