What is equivelant to 1/4 and 2/5

Step-by-step explanation:

The first step to adding fractions is reaching a common denominator. From there, we simply add and simplify if necessary. The steps for this problem are as follows…get to a common denominator of 20 by changing 1/4 to 5/20, and by changing 2/5 for 8/20. Since these fractions are equal to the previous it does not change the result of the problem.Add 5/20 + 8/20We then get to the result of 13/20 and since thirteen is a prime number we cannot simplify further.

Hope this helps!
