Question

I need the answer to this because I don't get it so can you please tell me what it is

Answer 1

2/5+1/2=9/10
You have to turn both fractions to common denominators, so that both fractions will be out of 10

2/5=4/10
1/2=5/10
4/10+5/10=9/10

Answer 2

2/5+1/2^2
2/5+2/4
multiply the first fraction by four and the second fraction by five to get the common denominator of 20
8/20+10/20=18/20
reduce
9/10

hope I helped !
