What is ${3} \dfrac{2}{7} - {2}\dfrac{1}{3}$?A. $\dfrac{20}{21}$ A. $\dfrac{20}{21}$ B. $ {1} \dfrac{20}{21}$ C. $ {2} \dfrac{20}{21}$ D. $ {4} \dfrac{20}{21}$ E. $ {3} \dfrac{20}{21}$
Show Answer Show The First Step 1. ${3} \dfrac{2}{7} - {2}\dfrac{1}{3}$$ = {3} + \dfrac{2}{7} - {2} - \dfrac{1}{3}$$ = {3} - {2}+ \dfrac{2}{7} - \dfrac{1}{3}$Show Next Step 2. $ = {1} + \dfrac{2}{7} - \dfrac{1}{3}$$ = \dfrac{7}{7} + \dfrac{2}{7} - \dfrac{1}{3}$Show Next Step 3. $ = \dfrac{{7}+{2}}{7} - \dfrac{1}{3}$$ = \dfrac{{9}}{7} - \dfrac{1}{3}$Show Next Step 4. $ =\dfrac{{9} \times {3}}{{7} \times {3}} - \dfrac{{1}\times {7}}{{3} \times {7}}$Show Next Step 5. $ = \dfrac{{27}}{{21}} - \dfrac{7}{21}$$ = \dfrac{{27}-{7}}{21}$$=\dfrac{20}{21}$ No More Steps Practice Again Correct! Nice work!
