Question

f it takes 6 hours for 20 learners to finish painting a house, how many learners will complete the job in 3 hours

Answer 1

40

Explanation:

This is a ratio that we can set up as follows and solve for x

`(3)/(6)` =
`(20)/(x)`

Multiply both sides by x

`(x)/(2)` = 20

Multiply both sides by 2

x = 40

Answer 2

it would take 40 learners to finish the job in 3 hours.
