The denominators are $6 = 3 \times 2, 4 = 2 \times 2 \mbox{ and } 8 = 2 \times 2 \times 2$ so a common denominator requires three twos and a three, that is a common denominator is $2 \times 2 \times 2 \times 3 = 24.$ Thus you have \[ \frac56 = \frac{20}{24}, \frac74 = \frac{42}{24}, \mbox{ and } \frac{13}{8} = \frac{39}{24}\] Now add these fractions and simplify if possible,
One way is to do them two at a time (the order does not matter and a careful choice may make it easier) 5/6 + 7/4 = ? Now add 13/8 to that. Or you can find a denominator common to all the fractions (here 24 is the smallest option) and rewrite using that denominator: 20/24 + 42/24 + 39/24 = (20+42+39)/24 Good Hunting!
