Question

A pizza has 3 toppings with no toppings overlapping. Pepperoni tops 1/3 of the pizza and mushroom top 2/5. The rest is topped with sausage. What fraction is topped with sausage? (please show work, if u don't that's fine too♡)

Answer 1

$\frac{1}{3} + \frac{2}{5} + x=1$
$x= 1- \frac{5}{15} - \frac{6}{15} = \frac{15}{15} - \frac{11}{15} = \frac{4}{15}$
Answer: Sausage tops $\frac{4}{15}$ of the pizza
