To add fractions it is necessary to find a common denominator.

Add 5/8 + 1/10

Convert to a common denominator. 5/8 becomes 50/80. 1/10 becomes 8/80

Now it is possible to add the fractions. (50 + 8)/80 = 58/80 = 29/40

How do you minnous fractions?

Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.
