What is ${6} \dfrac{3}{9} - {5}\dfrac{3}{4}$?A. $\dfrac{21}{36}$ A. $\dfrac{21}{36}$ B. $ {1} \dfrac{21}{36}$ C. $ {2} \dfrac{21}{36}$ D. $ {4} \dfrac{21}{36}$ E. $ {3} \dfrac{21}{36}$
Show Answer Show The First Step 1. ${6} \dfrac{3}{9} - {5}\dfrac{3}{4}$$ = {6} + \dfrac{3}{9} - {5} - \dfrac{3}{4}$$ = {6} - {5}+ \dfrac{3}{9} - \dfrac{3}{4}$Show Next Step 2. $ = {1} + \dfrac{3}{9} - \dfrac{3}{4}$$ = \dfrac{9}{9} + \dfrac{3}{9} - \dfrac{3}{4}$Show Next Step 3. $ = \dfrac{{9}+{3}}{9} - \dfrac{3}{4}$$ = \dfrac{{12}}{9} - \dfrac{3}{4}$Show Next Step 4. $ =\dfrac{{12} \times {4}}{{9} \times {4}} - \dfrac{{3}\times {9}}{{4} \times {9}}$Show Next Step 5. $ = \dfrac{{48}}{{36}} - \dfrac{27}{36}$$ = \dfrac{{48}-{27}}{36}$$=\dfrac{21}{36}$ No More Steps Practice Again Correct! Nice work!
