What is ${7} \dfrac{2}{9} - {6}\dfrac{3}{7}$?A. $\dfrac{50}{63}$ A. $\dfrac{50}{63}$ B. $ {1} \dfrac{50}{63}$ C. $ {2} \dfrac{50}{63}$ D. $ {4} \dfrac{50}{63}$ E. $ {3} \dfrac{50}{63}$
Show Answer Show The First Step 1. ${7} \dfrac{2}{9} - {6}\dfrac{3}{7}$$ = {7} + \dfrac{2}{9} - {6} - \dfrac{3}{7}$$ = {7} - {6}+ \dfrac{2}{9} - \dfrac{3}{7}$Show Next Step 2. $ = {1} + \dfrac{2}{9} - \dfrac{3}{7}$$ = \dfrac{9}{9} + \dfrac{2}{9} - \dfrac{3}{7}$Show Next Step 3. $ = \dfrac{{9}+{2}}{9} - \dfrac{3}{7}$$ = \dfrac{{11}}{9} - \dfrac{3}{7}$Show Next Step 4. $ =\dfrac{{11} \times {7}}{{9} \times {7}} - \dfrac{{3}\times {9}}{{7} \times {9}}$Show Next Step 5. $ = \dfrac{{77}}{{63}} - \dfrac{27}{63}$$ = \dfrac{{77}-{27}}{63}$$=\dfrac{50}{63}$ No More Steps Practice Again Correct! Nice work!
