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
