Question

`31/23 - ( 7/32 + 8/23)`

Answer 1

\(\dfrac{31}{23}-\left(\dfrac{7}{32}+\dfrac{8}{23}\right)\\ =\dfrac{31}{23}-\dfrac{7}{32}-\dfrac{8}{23}\\ =\left(\dfrac{31}{23}-\dfrac{8}{23}\right)-\dfrac{7}{32}\\ =\dfrac{23}{23}-\dfrac{7}{32}\\ =1-\dfrac{7}{32}\\ =\dfrac{32-7}{32}\\ =\dfrac{25}{32}\)

Answer 2

31/23 - (7/32 + 8/23)

= 31/23 - 8/23 - 7/32

= 1 - 7/32

= 25/32

Answer 3

`31/23 -(7/32 + 8/23)`

`= 31/23 -7/32 - 8/23`

`=(  31/23 -8/23)-7/32`

`= 23/23- 7/32`

`= 1-7/32`

`=32/32 -7/32`

`= 25/32`
