Write (−27) +(−27) +(−27) +(−27) \left( - \frac { 2 } { 7 } \right) + \left( - \frac { 2 } { 7 } \right) + \left( - \frac { 2 } { 7 } \right) + \left( - \frac { 2 } { 7 } \right) (−72) +(−72) +(−72) +(−72) as a multiplication problem.
A) 4(27) 4 \left( \frac { 2 } { 7 } \right) 4(72)
B) 2(27) 2 \left( \frac { 2 } { 7 } \right) 2(72)
C) 4(214) 4 \left( \frac { 2 } { 14 } \right) 4(142)
D) −4(27) - 4 \left( \frac { 2 } { 7 } \right) −4(72)
E) - 4(214) 4 \left( \frac { 2 } { 14 } \right) 4(142)

Final Answer :
D
Explanation :
When we add the four fractions, we get −27−27−27−27=−87.-\frac{2}{7} - \frac{2}{7} - \frac{2}{7} - \frac{2}{7} = -\frac{8}{7}.−72−72−72−72=−78. Writing this as a multiplication problem, we have −4⋅27=−87.-4 \cdot \frac{2}{7} = -\frac{8}{7}.−4⋅72=−78. Therefore, the best choice is D.
