Answer:
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
