Here are the solutions to the problems:

Part a· 2 steps

  1. Convert "of" to multiplication.

    13 of 15=13×15\frac{1}{3} \text{ of } 15 = \frac{1}{3} \times 15
  2. Multiply the fraction by the whole number.

    13×15=153=5\frac{1}{3} \times 15 = \frac{15}{3} = 5

    The value is 5\boxed{5}.

Part b7

  1. Convert "of" to multiplication.

    14 of 28=14×28\frac{1}{4} \text{ of } 28 = \frac{1}{4} \times 28
  2. Multiply the fraction by the whole number.

    14×28=284=7\frac{1}{4} \times 28 = \frac{28}{4} = 7

    The value is 7\boxed{7}.

Part c10.8

  1. Convert "of" to multiplication.

    15 of 54=15×54\frac{1}{5} \text{ of } 54 = \frac{1}{5} \times 54
  2. Multiply the fraction by the whole number.

    15×54=545\frac{1}{5} \times 54 = \frac{54}{5}
  3. Convert the improper fraction to a mixed number or decimal.

    545=1045 or 10.8\frac{54}{5} = 10 \frac{4}{5} \text{ or } 10.8

    The value is 10.8\boxed{10.8}.
