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
