Question

Margret painted 2/5 of her room in 1/2 hour. At what rate per hour did Margret paint her room?

Answer 1

Hi!

We will solve this using proportions, like this:

2/5 in 1/2 hours

x in 1 hour

______________

x = (1*2/5)/(1/2)

x = 2/5/1/2

x = 4/5

Margret paints her room at 4/5 of her room per hour.

Hope this helps!

Answer 2

2/5 = 1/2

4/5 = 2/2

So Margret painted her room at 4/5 of her room per hour
