A pizza is cut into five pieces. Four of the pieces are the same size, and the fifth size is .5 the size of each of the others.

Gemiola [76]

Answer:

1/10 of pizza

Step-by-step explanation:

Let x represent size of equal pieces.

We have been given that a pizza is cut into five pieces. Four of the pieces are the same size, and the fifth size is 0.5 the size of each of the others.

This means that size of small piece would be half the size of other pieces, that is $\frac{x}{2}$ .

Since the pizza is divided in 5 pieces, so we will divide $\frac{x}{2}$ by 5 as:

$\frac{\frac{x}{2}}{5}=\frac{x}{2\cdot5}=\frac{x}{10}=\frac{1}{10}x$

Therefore, the smallest piece is 1/10 of the pizza.
