3/5 - 3/10, first you have to find the common denominator.
It’s 10. 5 and 10 have both in common.
We leave 3/10 alone because if you times it by 1, the answer is going to be the same. 3 x 1 = 3 & 10 x 1 = 10.
3/5, we know the denominator have to be 10 so 3 x 2 and 5 x 2. It’s 6/10.
Now solve the common denominator, we going to subtract. 6/10 - 3/10
The answer is 3/10.
