3/4 of X = 15

Multiplying out gives;

3X = 4x15

3X= 60

X = 20

Therefore, 4/5 of 20

Putting X = 20 we have;

4/5 x 20 = 16

so the answer is 16

Oksanka [162]

24% of the cars were travelling above the speed limit.

Step-by-step explanation:

Given,

Total cars monitored = 25

Cars traveling above the speed limit = 6

Percent of cars traveling above speed limit = $\frac{Cars\ travelling\ above\ speed\ limit}{Total\ cars\ monitored}*100$

Percent of cars = $\frac{6}{25}*100\\$

$Percent\ of\ cars=\frac{600}{25}\\Percent\ of\ cars=24\%$

24% of the cars were travelling above the speed limit.
