What is ${9} \dfrac{1}{7} - {8}\dfrac{3}{7}$?A. $\dfrac{5}{7}$ A. $\dfrac{5}{7}$ B. $ {1} \dfrac{5}{7}$ C. $ {2} \dfrac{5}{7}$ D. $ {4} \dfrac{5}{7}$ E. $ {3} \dfrac{5}{7}$
Show Answer Show The First Step 1. ${9} \dfrac{1}{7} - {8}\dfrac{3}{7}$$ = {9} + \dfrac{1}{7} - {8} - \dfrac{3}{7}$$ = {9} - {8}+ \dfrac{1}{7} - \dfrac{3}{7}$Show Next Step 2. $ = {1} + \dfrac{1}{7} - \dfrac{3}{7}$$ = \dfrac{7}{7} + \dfrac{1}{7} - \dfrac{3}{7}$Show Next Step 3. $ = \dfrac{{7}+{1}}{7} - \dfrac{3}{7}$$ = \dfrac{{8}}{7} - \dfrac{3}{7}$Show Next Step 4. $ =\dfrac{{8} \times {1}}{{7} \times {1}} - \dfrac{{3}\times {1}}{{7} \times {1}}$Show Next Step 5. $ = \dfrac{{8}}{{7}} - \dfrac{3}{7}$$ = \dfrac{{8}-{3}}{7}$$=\dfrac{5}{7}$ No More Steps Practice Again Correct! Nice work!
