Step-by-Step Solution

To solve 45+13\frac{4}{5} + \frac{1}{3}, follow these steps:

  • Step 1: Identify a common denominator for the fractions. The current denominators are 55 and 33, hence their common denominator is 1515 (since 5×3=155 \times 3 = 15).
  • Step 2: Convert each fraction to an equivalent fraction with the common denominator 1515:
    • For 45\frac{4}{5}: multiply the numerator and the denominator by 33 (since 5×3=155 \times 3 = 15).
      45=4×35×3=1215\frac{4}{5} = \frac{4 \times 3}{5 \times 3} = \frac{12}{15}.
    • For 13\frac{1}{3}: multiply the numerator and the denominator by 55 (since 3×5=153 \times 5 = 15).
      13=1×53×5=515\frac{1}{3} = \frac{1 \times 5}{3 \times 5} = \frac{5}{15}.
  • Step 3: Add the converted fractions:
    1215+515=12+515=1715\frac{12}{15} + \frac{5}{15} = \frac{12 + 5}{15} = \frac{17}{15}.

Therefore, the solution to the problem is 1715\frac{17}{15}.

Answer

1715 \frac{17}{15}
