Example 1

easy
Add 125+2151\frac{2}{5} + 2\frac{1}{5}.

Solution

  1. 1
    Add the whole number parts: 1+2=31 + 2 = 3.
  2. 2
    Add the fraction parts (same denominator): 25+15=35\frac{2}{5} + \frac{1}{5} = \frac{3}{5}.
  3. 3
    Combine: 3+35=3353 + \frac{3}{5} = 3\frac{3}{5}.

Answer

3353\frac{3}{5}
When adding mixed numbers with like denominators, add the whole numbers and the fractions separately, then combine the results. This works because a mixed number is simply a whole number plus a fraction.
