Zgjidhja

  1. 18×83=1×11×3=13\dfrac{1}{\cancel{8}} \times \dfrac{\cancel{8}}{3} = \dfrac{1 \times 1}{1 \times 3} = \dfrac{1}{3}
  2. 15×54=1×11×4=14\dfrac{1}{\cancel{5}} \times \dfrac{\cancel{5}}{4} = \dfrac{1 \times 1}{1 \times 4} = \dfrac{1}{4}
  3. 114×73=1×12×3=16\dfrac{1}{\cancel{14}} \times \dfrac{\cancel{7}}{3} = \dfrac{1 \times 1}{2 \times 3} = \dfrac{1}{6}
  4. 110×52=1×12×2=14\dfrac{1}{\cancel{10}} \times \dfrac{\cancel{5}}{2} = \dfrac{1 \times 1}{2 \times 2} = \dfrac{1}{4}
  5. 23×43=2×43×3=89\dfrac{2}{3} \times \dfrac{4}{3} = \dfrac{2 \times 4}{3 \times 3} = \dfrac{8}{9}
  6. 58×97=5×98×7=4556\dfrac{5}{8} \times \dfrac{9}{7} = \dfrac{5 \times 9}{8 \times 7} = \dfrac{45}{56}
  7. 112×83=1×23×3=29\dfrac{1}{\cancel{12}} \times \dfrac{\cancel{8}}{3} = \dfrac{1 \times 2}{3 \times 3} = \dfrac{2}{9}
  8. 27×43=2×43×7=821\dfrac{2}{7} \times \dfrac{4}{3} = \dfrac{2 \times 4}{3 \times 7} = \dfrac{8}{21}
  9. 72154×3316=36×3377×16=9×37×4=2728\dfrac{\cancel{72}}{\cancel{154}} \times \dfrac{33}{16} = \dfrac{\cancel{36} \times \cancel{33}}{\cancel{77} \times \cancel{16}} = \dfrac{9 \times 3}{7 \times 4} = \dfrac{27}{28}
