What is ${4} \dfrac{4}{9} - {3}\dfrac{4}{8}$?A. $\dfrac{68}{72}$ A. $\dfrac{68}{72}$ B. $ {1} \dfrac{68}{72}$ C. $ {2} \dfrac{68}{72}$ D. $ {4} \dfrac{68}{72}$ E. $ {3} \dfrac{68}{72}$
Show Answer Show The First Step 1. ${4} \dfrac{4}{9} - {3}\dfrac{4}{8}$$ = {4} + \dfrac{4}{9} - {3} - \dfrac{4}{8}$$ = {4} - {3}+ \dfrac{4}{9} - \dfrac{4}{8}$Show Next Step 2. $ = {1} + \dfrac{4}{9} - \dfrac{4}{8}$$ = \dfrac{9}{9} + \dfrac{4}{9} - \dfrac{4}{8}$Show Next Step 3. $ = \dfrac{{9}+{4}}{9} - \dfrac{4}{8}$$ = \dfrac{{13}}{9} - \dfrac{4}{8}$Show Next Step 4. $ =\dfrac{{13} \times {8}}{{9} \times {8}} - \dfrac{{4}\times {9}}{{8} \times {9}}$Show Next Step 5. $ = \dfrac{{104}}{{72}} - \dfrac{36}{72}$$ = \dfrac{{104}-{36}}{72}$$=\dfrac{68}{72}$ No More Steps Practice Again Correct! Nice work!
