Question

一令纸有 $500$ 张，厚 $5$ 厘米。大约多少张这种纸叠起来会有 $7.5$ 厘米高？

A ream of paper containing $500$ sheets is $5$ cm thick. Approximately how many sheets of this type of paper would there be in a stack $7.5$ cm high?

$250$

$550$

$667$

$750$

$1250$

因为 $7.5$ 厘米是 $5$ 厘米的 $1.5$ 倍，所以纸张数也是 $1.5$ 倍。

也就是 $1.5 \times 500 = 750$ 张。

所以正确答案是 D。

Since $7.5$ cm is $1.5$ times $5$ cm, the stack holds $1.5$ times as many sheets.

That is $1.5 \times 500 = 750$ sheets.

Thus, the correct answer is D .
