We will discuss here about verification of equivalent fractions. To verify that two fractions are equivalent or not, we multiply the numerator of one fraction by the denominator of the other fraction. Similarly, we multiply the denominator of one fraction by the numerator of the other fraction. If the products obtained, are the same, the fractions are equivalent.
Consider the following examples.
1. Test whether 4/9 and 8/18 are equivalent or not.
Here, 4 × 18 = 72
(The product of the numerator of the first fraction and the denominator of the other)
9 × 8 = 72
(The product of the denominator of the first fraction and the numerator of the other)
Thus, 4/9 and 8/18 are equivalent fractions.
We can also verify equivalent fractions by reducing them to their lowest terms.
2. Test whether 2/3, 10/15 and 22/33 are equivalent or not.
We express the above fractions to their lowest terms.
2/3 is itself in its lowest terms. (The H.C.F. of 2 and 3 is 1)
10/15 = 10 ÷ 5/15 ÷ 5 = 2/3 and 22/33 = 22 ÷ 11/33 ÷ 11 = 2/3
Because 2/3, 10/15 and 22/33 have the same value. So, they are equivalent fractions.
