Answer 1

Answer: 1/ 40 x (-155x-184)

Answer 2

`:\quad (713)/(40)=17(33)/(40)`

Explanation:

`-3(7)/(8)* \:-4(3)/(5)\\\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad 3(7)/(8)=(31)/(8)\\-(31)/(8)* \:-4(3)/(5)\\\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad 4(3)/(5)=(23)/(5)\\-(31)/(8)* \:-(23)/(5)\\\mathrm{Apply\:rule}\:-\left(-a\right)=a\\=(31)/(8)* (23)/(5)\\\mathrm{Multiply\:fractions}:\quad (a)/(b)* (c)/(d)=(a\:* \:c)/(b\:* \:d)\\`

`=(31* \:23)/(8* \:5)\\\\=(713)/(40)\\\\\mathrm{Convert\:improper\:fractions\:to\:mixed\:numbers}:\\\quad (713)/(40)=17(33)/(40)`
