Question

Shira counted 330 cars passing through an intersection one afternoon. She found that 3 out of every 10 cars was an SUV. How many SUVs did Shira count through the intersection?

Answer 1

If 3 out of 10 cars were SUVs, that means the ratio is $\frac{3}{10}$

Just multiply that by the total number of cars:

$\frac{3}{10}*330 = 99$

So the answer is 99 SUVs
