1 whole thing = 6 sixths 3 whole things = 18 sixths
1 third of a whole thing = 2 sixths of it
3 wholes plus 1 third = 18 sixths plus 2 sixths =** 20 sixths **
Change 3 1/3 to improper fraction which equals 10/3. Then multiply numerator and denominator by 2 10/3 = 20/6, so there are 20 sixths in 3 and 1 third.
There are 20 sixths in 3 and 1 third. This is found by converting the mixed number to an improper fraction and then changing that fraction to sixths.
