What is ${7} \dfrac{2}{5} - {6}\dfrac{3}{6}$?A. $\dfrac{27}{30}$ A. $\dfrac{27}{30}$ B. $ {1} \dfrac{27}{30}$ C. $ {2} \dfrac{27}{30}$ D. $ {4} \dfrac{27}{30}$ E. $ {3} \dfrac{27}{30}$
Show Answer Show The First Step 1. ${7} \dfrac{2}{5} - {6}\dfrac{3}{6}$$ = {7} + \dfrac{2}{5} - {6} - \dfrac{3}{6}$$ = {7} - {6}+ \dfrac{2}{5} - \dfrac{3}{6}$Show Next Step 2. $ = {1} + \dfrac{2}{5} - \dfrac{3}{6}$$ = \dfrac{5}{5} + \dfrac{2}{5} - \dfrac{3}{6}$Show Next Step 3. $ = \dfrac{{5}+{2}}{5} - \dfrac{3}{6}$$ = \dfrac{{7}}{5} - \dfrac{3}{6}$Show Next Step 4. $ =\dfrac{{7} \times {6}}{{5} \times {6}} - \dfrac{{3}\times {5}}{{6} \times {5}}$Show Next Step 5. $ = \dfrac{{42}}{{30}} - \dfrac{15}{30}$$ = \dfrac{{42}-{15}}{30}$$=\dfrac{27}{30}$ No More Steps Practice Again Correct! Nice work!
