Question

Mr. Cabahug's soccer team scored 4 out of 9 goals in yesterday's game. If this rate was constant, how many goals will they miss out of 36 attempts?

Answer 1

If the rate is constant they will miss 20 out of 36 attempts.

Explanation:

Because the scored 4 out of 9 this means they missed 5 out of 9 (`9 - 4 = 5`)

We can write the ratio of misses as:

`5:9` is the same as `x:36`

We can write this as an equation and solve for `x`:

`5/9 = x/36`

`36 * 5/9 = 36 x/36`

`36/9 * 5 = x`

`4 * 5 = x`

`x = 20`
