Rules in adding fractions:

1) Make sure that they have common denominator.
5/10 + 3/10

2) Since both fraction have a denominator of 10, add the numerator and place the sum above the denominator

5/10 + 3/10 = (5 + 3)/10 = 8/10

3) Simplify the fraction
8/10 can still be simplified into 4/5

8 ÷ 2 = 4
10 ÷ 2 = 5

5/10 + 3/10 = 4/5
add 5+3= 8    then to make it in simplest form divide it by 2 until you can't
                  10     Your answer is 4/5
