Question

Write the fraction 1/4 and 7/22 as equivalent fractions with the least common denominator. ?

1/4=?
7/22=?

Answer 1

Explanation:

Four has 2 twos.

22 has 1 two and 1 eleven.

So the least common denominator is

2 * 2 * 11

44

1/4 has to have numerator and denominator multiplied by 11

1*11/4*11 = 11/44

7/22 needs just 1 two multiplied by the common 2 to make the denominator common

7*2 / 22*2 = 14 / 44
