Question

(617/191+29/33-115/117)x(1/4-1/5-1/20)

Answer 1

(617/191+29/33-115/117)*(1/4-1/5-1/20)

= (617/191+29/33-115/117)*(5/20-4/20-1/20)

=(617/191+29/33-115/117)*0

=0

Answer 2

\(\left(\dfrac{617}{191}+\dfrac{29}{33}-\dfrac{115}{117}\right)\times\left(\dfrac{1}{4}-\dfrac{1}{5}-\dfrac{1}{20}\right)\\ =\left(\dfrac{617}{191}+\dfrac{29}{33}-\dfrac{115}{117}\right)\times0\\ =0\)
