Question

The school band brought cheese and pepperoni pizzas in ratio represented in the tape diagram for their end of year party.

Answer 1

ANSWER

2 pepperoni pizzas

EXPLANATION

From the tape diagram, the ratio of cheese pizzas to pepperoni pizzas is:

3 : 1.

They bought 6 cheese pizzas.

Let the number of pepperoni pizzas be x.

So, by comparison, we have that:

3 : 1 = 6 : x

or

$\begin{gathered} \frac{3}{1}\text{ = }\frac{6}{x} \\ \text{Cross multiply to find x:} \\ 3\cdot\text{ x = 6 }\cdot\text{ 1} \\ \text{Divide through by 3:} \\ x\text{ = }\frac{6}{3} \\ x\text{ = 2} \end{gathered}$

Therefore, they bought 2 pepperoni pizzas.
