一部Gameboy的成本價是$500。一架模型車的價錢是Gameboy的3/4。一架搖控飛機的價錢是一架模型車的1 4/5。一架搖控飛機多少錢？
$500*3/4*1 4/5
=$500*3/4*9/5
=$675
$500*3/4*1 4/5
=$500*3/4*9/5
=$675

500 * 3/4 * 9/5=675
首先計左model car 幾錢！！
500 * 3/4 = 375
因為佢話model car ge價錢係gameboy ge 四分之三！！
之後再計aeroplane 幾錢！！
375 * 9/5 = 675 (1 4/5=9/5)
因為佢話aeroplane ge價錢係model car ge 五分之九！！
所以aeroplane 就係675元！！

1個遊戲機賣$500，
玩具車的價錢係遊戲機的3/4~
搖控飛機的價錢係車的1又4/5(我估)，
咁飛機幾錢呢?
SOLUTION:
price of model car= 500x 3/4= $375
the price of the aeroplane = 375x 1又4/5= 675
如果架飛機係4/5 of the model car，咁就= 375x4/5= $300

The model car costs:
=3/4 * $500
=$375
The aeroplane car costs:
( 1 4/5) * $375
=9/5 * $375
=$675
∴The aeroplane car costs $675.

最簡單既方法:$500 * 3/4 * ( 1 4/5)=$675但係冇咁清楚囉
=3/4 * $500
=$375
The aeroplane car costs:
( 1 4/5) * $375
=9/5 * $375
=$675
∴The aeroplane car costs $675.

一部gameboy 要500 蚊~ 一部玩具車就係一個gameboy 4份3 既錢
一部模型飛機既價錢就 係1又5份4 既 玩具車
咁一部飛機幾錢?
500X 3/4 X 1 4/5
就係咁喇
