Question

Ricky C's 的一个汉堡重 $120$ 克，其中 $30$ 克是填充物。汉堡中不是填充物的部分占百分之多少？

A burger at Ricky C's weighs $120$ grams, of which $30$ grams are filler. What percent of the burger is not filler?

$60 \%$

$65 \%$

$70 \%$

$75 \%$

$90 \%$

知识点：百分数

不是填充物的部分为 $120 - 30 = 90$ 克。因此百分比为 $100 \cdot \dfrac{90}{120} = 100 \cdot \dfrac{3}{4} = 75 \%.$

所以正确答案是 D。

We get that $120 - 30 = 90$ grams are not filler. The percentage is therefore $100 \cdot \dfrac{90}{120} = 100 \cdot \dfrac{3}{4} = 75 \%.$

Thus, D is the correct answer.
