Question

-15/4 . 9/11 + 15/4. 15/11 - 15/4 . 6/11

Answer 1

\(=\dfrac{-15}{4}.\dfrac{9}{11}+\dfrac{15}{4}.\dfrac{15}{11}-\dfrac{15}{4}.\dfrac{6}{11}\)

= \(\dfrac{15}{4}.\dfrac{-9}{11}+\dfrac{15}{4}.\dfrac{15}{11}-\dfrac{15}{4}.\dfrac{6}{11}\)

= \(\dfrac{15}{4}.\left(\dfrac{-9}{11}+\dfrac{15}{11}-\dfrac{6}{11}\right)\)

= \(\dfrac{15}{4}.\left(\dfrac{6}{11}-\dfrac{6}{11}\right)\)

= \(\dfrac{15}{4}.\left(\dfrac{0}{11}\right)\)

= \(\dfrac{15}{4}.0\)

= 0

Answer 2

=15/4*(-9/11+15/11-6/11)

=15/4*0=0
