Answer 5

4/10
4 and 10 are both even so that means they are both divisible by 2
4 divided by 2=2
10 divided by 2=5
so 4/10=2/5
so what is the question mark in: 2/5+?/5=3/5

Answer 6

Answer 7

since the denominators are the same on both the left hand side and the right hand side
then the sum of the numerators of the left hand side equals the numerator of the right hand side
so the 2/5+1/5=3/5
