What is ${9} \dfrac{3}{9} - {8}\dfrac{2}{5}$?A. $\dfrac{42}{45}$ A. $\dfrac{42}{45}$ B. $ {1} \dfrac{42}{45}$ C. $ {2} \dfrac{42}{45}$ D. $ {4} \dfrac{42}{45}$ E. $ {3} \dfrac{42}{45}$
Show Answer Show The First Step 1. ${9} \dfrac{3}{9} - {8}\dfrac{2}{5}$$ = {9} + \dfrac{3}{9} - {8} - \dfrac{2}{5}$$ = {9} - {8}+ \dfrac{3}{9} - \dfrac{2}{5}$Show Next Step 2. $ = {1} + \dfrac{3}{9} - \dfrac{2}{5}$$ = \dfrac{9}{9} + \dfrac{3}{9} - \dfrac{2}{5}$Show Next Step 3. $ = \dfrac{{9}+{3}}{9} - \dfrac{2}{5}$$ = \dfrac{{12}}{9} - \dfrac{2}{5}$Show Next Step 4. $ =\dfrac{{12} \times {5}}{{9} \times {5}} - \dfrac{{2}\times {9}}{{5} \times {9}}$Show Next Step 5. $ = \dfrac{{60}}{{45}} - \dfrac{18}{45}$$ = \dfrac{{60}-{18}}{45}$$=\dfrac{42}{45}$ No More Steps Practice Again Correct! Nice work!
