Question

Melinda paints 7/8 of a wall in 1 1/6 hours. What part of the wall does Melinda paitn in 1 minute?

Answer 1

how many minutes are there in 1 1/6 hours?

we count like this:

`1(1)/(6) *60= (7)/(6) *60=70`

so she can paint 7/8 wall in 70 minutes.

how much is it per minute?


`(7)/(8*70) = (1)/(8*10) = (1)/(80)`

and that's the correct answer!
