1 over 4 + 1 over 10

7/20

Step-by-step explanation:

Convert them so they have the same denominator.

1/4 + 1/10

A common denominator is 40 (I'm just choosing an easy one for now, rather than the smallest one)

1/4 * 10/10 = 10/40

1/10 * 4/4 = 4/40

10/40 + 4/40

Add the numerators

(10 + 4) / 40 = 14/40

Simplify the fraction

14/2 = 7 40/2 = 20

7/20
