What are two common denominators for 3/10 and 1/2

10,20

Step-by-step explanation:

What numbers do 2 and 10 both go into

2 and 10 both go into 10

10/2 = 5

10/10 = 1

So 1 common denominator is 10 (This is the least common denominator)

2 and 10 with both go into 20

20/2 = 10

20/10 = 2

A second common denominator is 20
