Question

Rod waxes two thirds of his car with one fourth bottle of car wax. What fraction of the bottle of car wax will Rod need to wax his entire car?

Answer 1

Answer is 3/8
Step by step

Use x for car wax

2/3x = 1/4 × 1 car
2/3x = 1/4

Divide both sides by 2/3 to solve for x

x = 1/4 divided by 2/3

Note to divide fractions flip the 2/3 and multiply

x = 1/4 × 3/2 multiply across

x = 3/8.
