What is ${7} \dfrac{3}{9} - {6}\dfrac{1}{2}$?A. $\dfrac{15}{18}$ A. $\dfrac{15}{18}$ B. $ {1} \dfrac{15}{18}$ C. $ {2} \dfrac{15}{18}$ D. $ {4} \dfrac{15}{18}$ E. $ {3} \dfrac{15}{18}$
Show Answer Show The First Step 1. ${7} \dfrac{3}{9} - {6}\dfrac{1}{2}$$ = {7} + \dfrac{3}{9} - {6} - \dfrac{1}{2}$$ = {7} - {6}+ \dfrac{3}{9} - \dfrac{1}{2}$Show Next Step 2. $ = {1} + \dfrac{3}{9} - \dfrac{1}{2}$$ = \dfrac{9}{9} + \dfrac{3}{9} - \dfrac{1}{2}$Show Next Step 3. $ = \dfrac{{9}+{3}}{9} - \dfrac{1}{2}$$ = \dfrac{{12}}{9} - \dfrac{1}{2}$Show Next Step 4. $ =\dfrac{{12} \times {2}}{{9} \times {2}} - \dfrac{{1}\times {9}}{{2} \times {9}}$Show Next Step 5. $ = \dfrac{{24}}{{18}} - \dfrac{9}{18}$$ = \dfrac{{24}-{9}}{18}$$=\dfrac{15}{18}$ No More Steps Practice Again Correct! Nice work!
