Question

If Alex ate $\frac{2}{4}th$ of the cheese pizza, $\frac{3}{8}th$ of the onion pizza, and $\frac{6}{16}th$ of the tomato pizza then what part of pizza is left on each plate?

Answer 1

We have to subtract all the fractions from each one whole pizza. For the first pizza we have 4 slices,
$1-\frac{2}{4}=\frac{4}{4}-\frac{2}{4}=\frac{4-2}{4}=\frac{2}{4}=\frac{1}{2}$

For the second pizza we have 8 slices,
$1-\frac{3}{8}=\frac{8}{8}-\frac{3}{8}=\frac{8-3}{8}=\frac{5}{8}$

For the third pizza we have 16 slices,
$1-\frac{6}{16}=\frac{16}{16}-\frac{6}{16}=\frac{16-6}{16}=\frac{10}{16}=\frac{5}{8}$

Hence, $\frac{1}{2}$ pizza in 1st plate, $\frac{5}{8}$ pizza in second plate and $\frac{5}{8}$ pizza in third plate are left.
