Question 50: Performing the calculation (frac{3}{5}:left( {frac{{ – 9}}{7}} right) – frac{7}{3} ) we get : A. ( – frac{{11}}{5}) B. ( – frac{{4}}{5}) C. ( – frac{{9}}{5}) D. ( – frac{{14}}{5}) We have (frac{3}{5}:left( {frac{{ – 9}}{7}} right) – frac{7}{3} = frac{3}{5}. left( { – frac{7}{9}} right) – frac{7}{3} = frac{{ – 7}}{{15}} – …
