What is ${6} \dfrac{1}{7} - {5}\dfrac{4}{5}$?A. $\dfrac{12}{35}$ A. $\dfrac{12}{35}$ B. $ {1} \dfrac{12}{35}$ C. $ {2} \dfrac{12}{35}$ D. $ {4} \dfrac{12}{35}$ E. $ {3} \dfrac{12}{35}$
Show Answer Show The First Step 1. ${6} \dfrac{1}{7} - {5}\dfrac{4}{5}$$ = {6} + \dfrac{1}{7} - {5} - \dfrac{4}{5}$$ = {6} - {5}+ \dfrac{1}{7} - \dfrac{4}{5}$Show Next Step 2. $ = {1} + \dfrac{1}{7} - \dfrac{4}{5}$$ = \dfrac{7}{7} + \dfrac{1}{7} - \dfrac{4}{5}$Show Next Step 3. $ = \dfrac{{7}+{1}}{7} - \dfrac{4}{5}$$ = \dfrac{{8}}{7} - \dfrac{4}{5}$Show Next Step 4. $ =\dfrac{{8} \times {5}}{{7} \times {5}} - \dfrac{{4}\times {7}}{{5} \times {7}}$Show Next Step 5. $ = \dfrac{{40}}{{35}} - \dfrac{28}{35}$$ = \dfrac{{40}-{28}}{35}$$=\dfrac{12}{35}$ No More Steps Practice Again Correct! Nice work!
