Question

A school tested all of their 250 lights and 16 of them were faulty.Find the percentage of lights that were faulty (do not round your answer)

Answer 1

6.4% of the lights are faulty

Explanation:

Well you can make a proportion out of this question.
so lets do faulty/total

16/250 = x/ 100

Since x/100 is basically finding the percent since percent means out of a hundred.

Cross multiply to solve.

250x= 1600

SOlve for x

X=6.4

6.4 percent of the lights are faulty.
