Answer:

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

Answer: Two common denominators for 3/10 & 1/2 is 10 and 20.


Explanation: If you multiply the denominator in 1/2 (2) by 5 you get 10.. So that's 1 common denominator. If you multiply the denominator in 3/10 (10) by 2 you get 20. Never did well in this section of math. Let me know if it worked out or not if you can!!


Happy Mathing!!
