Answer 1

✰✰|| Given ||✰✰

• A : B = 3 : 4

• B : C = 6 : 7

✰✰|| To Find ||✰✰

• A : B : C

• A : C

✪|| Solution ||✪

A : B : C = product of numerator : 1st denominator × 2nd numerator : product of denominator

➻ A : B : C = 3 × 6 : 4 × 6 : 4 × 7

➻ A : B : C = 18 : 24 : 28

value of A = 18

value of B = 24

Value of C = 28

A : C = 18 : 28

Value of A : B : C is 18 : 24 : 28 and A : C is 18 : 28
