How can seven one-third treat pieces make more than one whole? Group three, three, and one: two wholes, one third. Divide numerator by denominator: quotient means whole groups; remainder means leftover numerator. Keep the denominator. Eight thirds make two and two thirds; eleven fifths make two and one fifth. The same pieces can be grouped into wholes or counted back into one total. Multiply the whole number by the denominator, add the numerator, and keep the denominator: three and one fourth is thirteen fourths; two and two fifths is twelve fifths. Nine halves is four and one half; thirteen fourths is three and one fourth; two and three fifths is thirteen fifths; four and two fifths is twenty-two fifths. So seven thirds make two wholes and one third.
