What is ${9} \dfrac{1}{8} - {8}\dfrac{2}{5}$?A. $\dfrac{29}{40}$ A. $\dfrac{29}{40}$ B. $ {1} \dfrac{29}{40}$ C. $ {2} \dfrac{29}{40}$ D. $ {4} \dfrac{29}{40}$ E. $ {3} \dfrac{29}{40}$
Show Answer Show The First Step 1. ${9} \dfrac{1}{8} - {8}\dfrac{2}{5}$$ = {9} + \dfrac{1}{8} - {8} - \dfrac{2}{5}$$ = {9} - {8}+ \dfrac{1}{8} - \dfrac{2}{5}$Show Next Step 2. $ = {1} + \dfrac{1}{8} - \dfrac{2}{5}$$ = \dfrac{8}{8} + \dfrac{1}{8} - \dfrac{2}{5}$Show Next Step 3. $ = \dfrac{{8}+{1}}{8} - \dfrac{2}{5}$$ = \dfrac{{9}}{8} - \dfrac{2}{5}$Show Next Step 4. $ =\dfrac{{9} \times {5}}{{8} \times {5}} - \dfrac{{2}\times {8}}{{5} \times {8}}$Show Next Step 5. $ = \dfrac{{45}}{{40}} - \dfrac{16}{40}$$ = \dfrac{{45}-{16}}{40}$$=\dfrac{29}{40}$ No More Steps Practice Again Correct! Nice work!
