Question

Express the fractions 3/4,7/16 and 5/8 with LCD

Answer 1

The least common multiple of the three denominators is 16 because:

`4 * 4 = 16 \\ 16 * 1 = 16 \\ 8 * 2 = 16`

Change the fractions so that each fraction has a denominator of 16.

`(3 * 4)/(4 * 4) = (12)/(16)`

`(7 * 1)/(16 * 1) = (7)/(16)`

`(5 * 2)/(8 * 2) = (10)/(16)`

____________________________________________________

`1. (12)/(16) \\ \\ 2. (7)/(16) \\ \\ 3. (10)/(16)`
