Question

A contaminant is found in a solution at a level of 3/500%. What fraction of the solution is this

Answer 1

Answer:3/5

Step-by-step explanation:

First we change 500% to fractions

Changing percentage to fraction is dividing the number by 100

500% = 500/100

Putting this we get 3/(500/100)

Then when a number is being divided by a fraction, to get the answer, we multiply the number by the inverse of the fraction

3/(500/100) = 3 x 100/500 = 300/500 = 3/5
