Question

Suzzane can work 10 math problems in 15 minutes. How many can she word in an hour and a half?

Answer 1

`60`

Explanation:

Suzzane can work 10 math problems in 15 minutes. We need to use proportion and raito.

One hour and a half is equal to 90 minutes. But to equal out the math problem, change it to 900.

So:

`(10)/(15)`
`= (x)/(900)`

`= 60`
