# Prepare a Presentation

- Explain how you solved each problem and why your answer makes sense.
- Explain Jan’s and Carlos’s methods.

# Challenge Problem

Denzel uses the following shortcut to divide a whole number by a fraction:

“To divide a whole number by a fraction, I multiply the whole number by the denominator of the fraction, and then divide this product by the numerator of the fraction.”

- Show that Denzel’s method works for the problems from today’s lesson: $3\xf7\frac{1}{4}$, $2\xf7\frac{3}{5}$, and $3\xf7\frac{2}{3}$.
- Why does Denzel’s shortcut work? Explain the mathematics of his method.
