A pizza is divided into 8 equal slices. If you eat 3 slices and your friend eats 2 slices, what fraction of the pizza is left? (4 marks)

1 answer

To determine the fraction of the pizza that is left after you and your friend have eaten, let's follow these steps:

  1. Total slices of pizza: There are 8 equal slices in a whole pizza.

  2. Total slices eaten: You ate 3 slices and your friend ate 2 slices. Therefore, the total number of slices eaten is: \[ 3 + 2 = 5 \text{ slices} \]

  3. Remaining slices: To find out how many slices are left, subtract the total slices eaten from the total slices: \[ 8 - 5 = 3 \text{ slices} \]

  4. Fraction of the pizza left: The fraction of the pizza that is remaining can be calculated by dividing the number of remaining slices by the total number of slices: \[ \text{Fraction left} = \frac{\text{Remaining slices}}{\text{Total slices}} = \frac{3}{8} \]

Thus, the fraction of the pizza that is left is \(\frac{3}{8}\).
