36.25

Percentage Calculation: Find 65% of 65

First, calculate 65% of 65. This involves multiplying 65 by the decimal equivalent of 65%, which is 0.65.

  • Calculation: $65\% \text{ of } 65 = 0.65 \times 65
  • Result: $0.65 \times 65 = 42.25

Fraction Calculation: Find $\frac{2}{5}$ of 15

Next, calculate $\frac{2}{5}$ of 15. This involves multiplying the fraction by the number.

  • Calculation: $\frac{2}{5} \times 15
  • Result: $\frac{2 \times 15}{5} = \frac{30}{5} = 6

Difference Calculation: Compare Values

Finally, find by how much the first value (65% of 65) is greater than the second value ($\frac{2}{5}$ of 15). Subtract the second value from the first.

  • Difference: $42.25 - 6
  • Result: $42.25 - 6 = 36.25

Therefore, 65% of 65 is greater than $\frac{2}{5}$ of 15 by 36.25.
