%281%261%2F2%29%2A%283%261%2F6%29%2B%281%261%2F2%29%2A%282%265%2F8%29

Change to improper fractions:

%283%2F2%29%2819%2F6%29%2B%283%2F2%29%2821%2F8%29

57%2F12%2B63%2F16

Reduce 57%2F12 to 19%2F4 by dividing top and bottom by 3
or you could have canceled in the preceding step.

19%2F4%2B63%2F16

The least common denominator of 4 and 16 is 16

Make the denominator in the first fraction become 16,
by multiplying by 4/4
