Question

Answer 1

\(C=\dfrac{59}{10}:\dfrac{3}{2}-\left(\dfrac{7}{3}.\dfrac{9}{2}-2.\dfrac{7}{3}\right):\dfrac{7}{4}\\ =\dfrac{59}{15}-\left(\dfrac{7}{3}.\left(\dfrac{9}{2}-2\right)\right):\dfrac{7}{4}\\ =\dfrac{59}{15}-\dfrac{7}{3}.\dfrac{5}{2}:\dfrac{7}{4}\\ =\dfrac{59}{15}-\dfrac{35}{6}:\dfrac{7}{4}\\ =\dfrac{59}{15}-\dfrac{10}{3}\\ =\dfrac{59-50}{15}\\ =\dfrac{9}{15}\\ =\dfrac{3}{5}\)

Answer 2

`C=5 9/10 : 3/2 - ( 2 1/3 xx 4 1/2 - 2 xx 2 1/3):7/4`

`=59/10 : 3/2 - (7/3 xx 9/2 - 2 xx 7/3): 7/4`

`=59/10 : 3/2 - [7/3 xx (9/2-2)]:7/4`

`=59/10 : 3/2 -[7/3 xx (9/2-4/2)]:7/4`

`=59/10:3/2-[7/3 xx5/2] : 7/4`

`=59/10 : 3/2 - 35/6:7/4`

`=59/10 xx 2/3 - 35/6 xx 4/7`

`=59/15 - 10/3`

`=59/16 - 50/15`

`=(59-50)/15`

`=9/15`

`=3/5`
