Step-by-Step Solution

To solve the subtraction of these two fractions, we'll follow these steps:

  • Step 1: Find a common denominator for the fractions 45 \frac{4}{5} and 13 \frac{1}{3} . The denominators are 5 and 3, and multiplying them gives us a common denominator of 15.
  • Step 2: Convert each fraction to have this common denominator:
    • Convert 45 \frac{4}{5} to an equivalent fraction with a denominator of 15. To do this, multiply both the numerator and the denominator by 3: 45=4×35×3=1215\frac{4}{5} = \frac{4 \times 3}{5 \times 3} = \frac{12}{15}.
    • Convert 13 \frac{1}{3} to an equivalent fraction with a denominator of 15. To do this, multiply both the numerator and the denominator by 5: 13=1×53×5=515\frac{1}{3} = \frac{1 \times 5}{3 \times 5} = \frac{5}{15}.
  • Step 3: Perform the subtraction of the numerators, now having the same denominator: 1215515=12515=715\frac{12}{15} - \frac{5}{15} = \frac{12 - 5}{15} = \frac{7}{15}.
  • Step 4: Simplify the result, if possible. In this case, 715\frac{7}{15} is already in its simplest form as 7 and 15 have no common factors other than 1.

Therefore, the solution to the problem is 715\frac{7}{15}.

Answer

715 \frac{7}{15}
