Question

What are the fractions Eleven-twelfths and Seven-fifteenths written with a common denominator?

Answer 1

55/60 and 28/60

Explanation:

the LCM of 12 and 15 is 60.

since 60= 12xFIVE you also need to multiply the 11xFIVE

that is 55. you have 55/60

and since 60=15xFOUR you also need to multiply the 7xFOUR that is 28. you have 28/60
