It takes Marty 1 1/4 hours to get ready for school. If 1/5 used to take shower and 1/3 is used to eat breakfast, how long does it take him to shower and eat breakfast?

Answer:8/15 of an hour or. 53 hours or 32 minutes

Step-by-step explanation:

You need common denominators to answer.

One way to get the CD is to multiply all the denominators together to get one CD

5/4 - 1/5 - 1/3

5/4 = 5*15/4*15. = 75/60

1/5 = 1*12/5*12 = 12/60

1/3 = 1*20/3*20 = 20/60

How long to eat and shower? 12/60 + 20/60 = 32/60

Reduce 32/60 to. 53 hours which is. 53 hours to do both

or 32/4=8, 60/4=15 so 8/15 If you need fractional form

Also if need minutes 8/15 = x/60

Crooks multiply and divide the proportions to get 32 minutes
