  1. 58×14=5×14×8=532\dfrac{5}{8} \times \dfrac{1}{4} = \dfrac{5 \times 1}{4 \times 8} = \dfrac{5}{32}
  2. 34×16=14×12=1×14×2=18\dfrac{\cancel{3}}{4} \times \dfrac{1}{\cancel{6}} = \dfrac{1}{4} \times \dfrac{1}{2} = \dfrac{1 \times 1}{4 \times 2} = \dfrac{1}{8}
  3. 23×17=2×13×7=221\dfrac{2}{3} \times \dfrac{1}{7} = \dfrac{2 \times 1}{3 \times 7} = \dfrac{2}{21}
  4. 316×19=116×13=1×116×3=148\dfrac{\cancel{3}}{16} \times \dfrac{1}{\cancel{9}} = \dfrac{1}{16} \times \dfrac{1}{3} = \dfrac{1 \times 1}{16 \times 3} = \dfrac{1}{48}
  5. 4×5=204 \times 5 = 20
  6. 6×32=3×3=9\cancel{6} \times \dfrac{3}{\cancel{2}} = 3 \times 3 = 9
  7. 5×52=5×52=2525 \times \dfrac{5}{2} = \dfrac{5 \times 5}{2} = \dfrac{25}{2}
  8. 11×73=11×73=77311 \times \dfrac{7}{3} = \dfrac{11 \times 7}{3} = \dfrac{77}{3}
  9. 51×317=3×3=9\cancel{51} \times \dfrac{3}{\cancel{17}} = 3 \times 3 = 9
