Question

I DO REALLY NEED HELP: An architect is planning a city parking lot. For every 12 commuters, the parking lot will need 5 parking spaces. How many parking spaces will be needed by 132 commuters?

Answer 1

It should be 46. Good luck

Answer 2

55 parking spaces

Explanation:

Using unitary method:

For every 12 commuters , 5 spaces are needed.

∴ For 1 commuter:

5 ÷ 12 ⇒
`(5)/(12)` spaces are needed.

∴ For 132 commuters ⇒
`(5)/(12)` × 132 = 55 spaces.
