There are 40 sport cars. %15 are yellow. How many cars are yellow sports cars?

Hi MG

It is easier and better jsut to say

15% of 40 = 15/100 * 40 = 15/10*4 = 60/10 = 6

Of course it is even easier if you use a calc.

6 cars are yellow 

Workings.

15% = 15/100 = 3/20

40 cars / 20 = 2 

2 cars * 3 = 6

In total 6 cars.
