Answer 1

最佳解答

超市售賣大型裝和普通裝两種花生油，普通裝花生油的花生油量比大型裝小 40 %，它們的體積差異為 600 毫升，求普通裝花生油的體積。

設大型裝花生油 的體積為 X

0.4X = 600 [40% = 0.4]

X = 600/0.4 = 1500 mL

0.6 X = 900 mL[普通裝花生油的體積 = 0.6X]

Answer 2

開心貓，很久不見了～

郭老師做得很好～

我可以解釋一下：

The volume of normal-sized peanut oil is 40% less than that of jumbo-sized peanut oil.

意思是：

普通裝的花生油體積比珍寶裝的少 40%。

如果你設了珍寶裝的體積是 X 毫升，那麼

普通裝的花生油體積 = (1 - 40%)X = 0.6X

X - 0.6X = 600

0.4X = 600

X = 1500

0.6X = 900
