Since 4 is only 2/3 of 6, then you need to divide 60 into 3rds.
1/3 of 60=20
60+20=80!
Hopefully this is correct, but i will go check real quick!
Multiply 5 and 8 by 10 and put back in fraction then 6 and 10 by 8 and put back in fraction then add numerators
The answer is B. x = 45 and y = 20
Yup, you got them all. (:
