Question

Answer 1

`e)`\(\dfrac{-1}{4}\cdot\dfrac{152}{11}+\dfrac{68}{4}\cdot\dfrac{-1}{11}+\dfrac{-22}{11}=\dfrac{-1\cdot152}{4.11}+\dfrac{-1.68}{4\cdot11}+\dfrac{-1\cdot22}{11}\)

\(=\dfrac{-1}{11}\cdot38+\dfrac{-1}{11}\cdot17+\dfrac{-1}{11}\cdot22=\dfrac{-1}{11}\cdot\left(38+17+22\right)\)

`=(-1)/11 *77`

`=-77/11 =-7`

Answer 2

e, -7
