Question

Lea has 3/4 cup of laundry detergent left in detergent bottle. Each load of laundry requires 1/6 cup of detergent. How many loads of laundry can Lea wash.

Answer 1

ANSWER

Lea can wash 4½ loads of laundry with the remaining detergent.

Step-by-step explanation

Quantity of detergent left

`= (3)/(4)`

Quantity required to watch each load

`= (1)/(6)`

Number of loads Lea can wash

`= (3)/(4) / (1)/(6)`

We now simplify this by multiplying with the reciprocal

Number of loads Lea can wash


`= (3)/(4) * (6)/(1)`


`= (3)/(2) * (3)/(1)`


`= (9)/(2)`


`= 4 (1)/(2)`

Therefore Lea can wash 4½ loads of laundry with the remaining detergent.
