Question

Victoria's fans the two spinner shown 500 times. Solve a proportion to predict the number of times the sum is 4, 5, or 6. Enter the credit answers in the boxes.

Answer 1

To get a sum of 4,

We need to establish a proportion

For the first spin

The values are 1, 2, 3, 4, 5,

Second spin 2

The values are 1, 2, and 3

Establishing a proportion

$\begin{gathered} \frac{4}{2}\text{ = }\frac{x}{2} \\ \text{Cross multipy} \\ 4\text{ x 2 = x }\cdot\text{ 2} \\ 8\text{ = 2x} \\ \text{Divide both sides by 2} \\ \frac{8}{2}\text{ = }\frac{2x}{2} \\ x\text{ = 4} \\ \end{gathered}$
