Question

Check through cross multiplication whether the following pairs of fractions are equivalent. (a) 3/5 and 6/10 (b) 7/8 and 15/16

Answer 1

Answer:3/5 and 6/10 = 30=30

Answer 2

Thus 3/5 and 6/10 are pairs of fractions that are equivalent.

Explanation:

a) 3 / 5 =  6 / 10

by cross multiplying,

3*10 = 5*6

=> 30=30

RHS = LHS.

hence 3/5 = 6/10 are equivalent

b) 7/8 = 15/16

by cross multiplying,

7*16 = 8*15

=> 112 ≠ 120

RHS ≠ LHS

hence 7/8 ≠ 15/16  is not equivalent
