Pam is painting a total of 45 square feet in her bedroom. If she has painted 60% so far, how many square feet of the bedroroom does Pam still need to paint?

Respuesta :

Since she has painted 60% of her bedroom so far, 40% must remain. In order to know how many square feet that is, we take the total amount of square feet she needs to paint and multiply it by 0.4

45*0.4 = 18 square feet
To find the answer: 
 
    60% of 45 = 27
 45 - 27 = 18

Or:

40% of 45 = 18
