What minus 3/10 equals 1/5

(3/10) - (1/5) = (1/10)

Explanation:

Make sure both fractions have the same denominator. 1/5 would turn into 2/10, and 3/10 would stay the same. When the denominators are equal, subtract the numerators to get the answer.

1/5 = 2/10

(3/10) - (2/10) = (1/10)

3/10 minus 1/5 equals 1/10
