Question

Tim earns $18 cleaning a home. How many homes did he clean, if he made 90 dollars?​

Answer 1

`x = 5`

Explanation:

From the given:

$18 ——→ 1 home

$90 ——→ x home

Cross multiply the above and make x the subject of formula.

`18x = 90`

Now, divide both sides by 18 to find the value of x.

`(18x)/(18) = (90)/(18)`

Therefore:

Tim made $90 from cleaning 5 homes.

Answer 2

Given ,

Tim earns $18 cleaning a home

Also , he made a total of $90

So now , Number of homes cleaned by him = No.of.Dollar earned by him divided by number of dollars he got from a single home

=> Number of house = 90/18 = 5

Hence , Tim cleaned 5 houses and made 90$
