Question

\(\dfrac{96.24+192.25+288.9-96}{32.72+64.14}\)

Answer 1

\(=\dfrac{96\left(24-1\right)+192\left(25+13.5\right)}{32\left(72+28\right)}\)

\(=\dfrac{96\left(23+50+27\right)}{32\cdot100}=3\)

Answer 2

\(\dfrac{96.24+192.25+288.9-96}{32.72+64.14}\)

\(=\dfrac{96.24+96.2.25+96.3.9-96.1}{32.72+32.2.14}\)

\(=\dfrac{96.\left(24+50+27-1\right)}{32.\left(72+28\right)}\)

\(=\dfrac{96.100}{32.100}\)

\(=3\)

Answer 3

`(96 . 24 + 192 . 25 + 288 . 9 - 96)/(32 . 72 + 64 . 14)`

`= (96 . 24 + (192:2) . (25 . 2) + (288:3) . (9 . 3) - 96 . 1)/(32 . 72 + (64:2) . (14 .2))`

`= (96 . 24 + 96 . 50 + 96 . 27 - 96 . 1)/(32 . 72 + 32 . 28)`

`= (96 . (24+50+27-1))/(32 . (72+28))`

`= (96 . 100)/(32 . 100)`

`= 9600/3200`

`= 3`
