What is ${3} \dfrac{3}{7} - {2}\dfrac{1}{2}$?A. $\dfrac{13}{14}$ A. $\dfrac{13}{14}$ B. $ {1} \dfrac{13}{14}$ C. $ {2} \dfrac{13}{14}$ D. $ {4} \dfrac{13}{14}$ E. $ {3} \dfrac{13}{14}$
Show Answer Show The First Step 1. ${3} \dfrac{3}{7} - {2}\dfrac{1}{2}$$ = {3} + \dfrac{3}{7} - {2} - \dfrac{1}{2}$$ = {3} - {2}+ \dfrac{3}{7} - \dfrac{1}{2}$Show Next Step 2. $ = {1} + \dfrac{3}{7} - \dfrac{1}{2}$$ = \dfrac{7}{7} + \dfrac{3}{7} - \dfrac{1}{2}$Show Next Step 3. $ = \dfrac{{7}+{3}}{7} - \dfrac{1}{2}$$ = \dfrac{{10}}{7} - \dfrac{1}{2}$Show Next Step 4. $ =\dfrac{{10} \times {2}}{{7} \times {2}} - \dfrac{{1}\times {7}}{{2} \times {7}}$Show Next Step 5. $ = \dfrac{{20}}{{14}} - \dfrac{7}{14}$$ = \dfrac{{20}-{7}}{14}$$=\dfrac{13}{14}$ No More Steps Practice Again Correct! Nice work!
