Question

3/7 = x/42

Fill in the blank to make the two fractions equivalent.

Answer 1

x = 18

Explanation:

multiplying the denominator of 7 by 6 gives 42, the denominator of the fraction on the right side.

Since the fractions are equal we must then multiply the numerator of the fraction on the left by 6

3 × 6 = 18 ⇒ x = 18
