What is ${6} \dfrac{1}{7} - {5}\dfrac{1}{6}$?A. $\dfrac{41}{42}$ A. $\dfrac{41}{42}$ B. $ {1} \dfrac{41}{42}$ C. $ {2} \dfrac{41}{42}$ D. $ {4} \dfrac{41}{42}$ E. $ {3} \dfrac{41}{42}$
Show Answer Show The First Step 1. ${6} \dfrac{1}{7} - {5}\dfrac{1}{6}$$ = {6} + \dfrac{1}{7} - {5} - \dfrac{1}{6}$$ = {6} - {5}+ \dfrac{1}{7} - \dfrac{1}{6}$Show Next Step 2. $ = {1} + \dfrac{1}{7} - \dfrac{1}{6}$$ = \dfrac{7}{7} + \dfrac{1}{7} - \dfrac{1}{6}$Show Next Step 3. $ = \dfrac{{7}+{1}}{7} - \dfrac{1}{6}$$ = \dfrac{{8}}{7} - \dfrac{1}{6}$Show Next Step 4. $ =\dfrac{{8} \times {6}}{{7} \times {6}} - \dfrac{{1}\times {7}}{{6} \times {7}}$Show Next Step 5. $ = \dfrac{{48}}{{42}} - \dfrac{7}{42}$$ = \dfrac{{48}-{7}}{42}$$=\dfrac{41}{42}$ No More Steps Practice Again Correct! Nice work!
