first you have to take the mixed numbers and turn them into common fractions
22/3 and 23/6
then you take the 22/3 and multiply it by 2 so that the two fractions have the same denominator
44/6 then you have to subtract 23/6 from 44/6 and turn it back into a mixed number
44/6-23/6= 21/6---> 3 3/6 ---> 3 1/2
