Question

If customer A has an appointment 2 2/3 hours before customer B who has an appointment 5/6 of an hour before customer C. How much later is customer C‘s appointment than customer A’s?

Answer 1

Simple addition and fractions.

First make the fractions have the same denominator by multiplying 2/3 by 2.

this yields:
2 4/6 + 5/6

you can even add the 2 to the 6ths.

16/6 + 5/6 = 21/6
or
3 3/6
or
3 1/2 hours
