Multiply, simplify to lowest terms, and write as a mixed number:
WHOLE_1fraction(NUM_1, DENOM_1, false, true) \times
WHOLE_2fraction(NUM_2, DENOM_2, false, true)
WHOLE_3 + NUM_3_SIMP / DENOM_3_SIMP
\qquad = fraction(I_NUM_1, DENOM_1, false, true) \times fraction(I_NUM_2, DENOM_2, false, true)
\qquad = \dfrac{I_NUM_1 \times I_NUM_2}{DENOM_1 \times DENOM_2}
\qquad = fraction(I_NUM, I_DENOM)
\qquad = fractionReduce(I_NUM, I_DENOM)
\qquad = WHOLE_3 fractionReduce(NUM_3, I_DENOM)
