What is ${7} \dfrac{3}{7} - {6}\dfrac{4}{8}$?A. $\dfrac{52}{56}$ A. $\dfrac{52}{56}$ B. $ {1} \dfrac{52}{56}$ C. $ {2} \dfrac{52}{56}$ D. $ {4} \dfrac{52}{56}$ E. $ {3} \dfrac{52}{56}$
Show Answer Show The First Step 1. ${7} \dfrac{3}{7} - {6}\dfrac{4}{8}$$ = {7} + \dfrac{3}{7} - {6} - \dfrac{4}{8}$$ = {7} - {6}+ \dfrac{3}{7} - \dfrac{4}{8}$Show Next Step 2. $ = {1} + \dfrac{3}{7} - \dfrac{4}{8}$$ = \dfrac{7}{7} + \dfrac{3}{7} - \dfrac{4}{8}$Show Next Step 3. $ = \dfrac{{7}+{3}}{7} - \dfrac{4}{8}$$ = \dfrac{{10}}{7} - \dfrac{4}{8}$Show Next Step 4. $ =\dfrac{{10} \times {8}}{{7} \times {8}} - \dfrac{{4}\times {7}}{{8} \times {7}}$Show Next Step 5. $ = \dfrac{{80}}{{56}} - \dfrac{28}{56}$$ = \dfrac{{80}-{28}}{56}$$=\dfrac{52}{56}$ No More Steps Practice Again Correct! Nice work!
