Okay well the way I do it is like this. When ever the next hour hits 10 minutes that is one hour then add the minutes left. So from 7:10a.m. to 6:10p.m. is 11 hours. Now the rest of the minutes. 6:35 -6:10=:25. So she has been away from the house for 11 hours and 25 minutes
I believe that it's -150.1
So she has 45 songs

Create a proportion for x first. Use known values.
84 = 12x

Create a proportion for y.
120 = 4y
Divide both sides by 4.
y = 30
