How do you solve equations like this: 7 5/6? can someone explain it?

(7 5/6 is just an example)

A b/c is a mixed number, we can turn a mixed number into its simplest form in this way:

a b/c = a + b/c = (a*c+b) / c

In this case:

7 5/6=7 + 5/6 = (7*6+5) / 6 = (42+5) / 6=47/6

Therefore: 7 5/6 = 47/6
