2/5= .4

.25+.4 = .65

65/100 = 13/20

Fraction:
1/4 + 2/5

5/20 + 8/20 = 13/20

Answer:
13/20

Answer 2

13/20

Explanation:

To figure this out, all you need to do is to add 1/4 and 2/5 together. But to do this you first need to find a common denominator. I used 20 as the common denominator, so now the two fractions are 1/4=5/20 and 2/5=8/20. Now that we have a common denominator, all you have to do it 5/20+8/20=13/20.
