Question

一罐汽水有 $12$ 盎司。要提供一加仑（ $128$ 盎司）汽水，至少需要多少罐？

One can holds $12$ ounces of soda. What is the minimum number of cans needed to provide a gallon ( $128$ ounces) of soda?

$7$

$8$

$9$

$10$

$11$

用 $128$ 除以 $12$ 。

Divide $128$ by $12$

最后一罐即使没有装满，也仍然算作一整罐。

A partly filled last can still counts as a whole can

因为 $\dfrac{128}{12} = 10\dfrac{2}{3}$ ，十罐只能装 $120$ 盎司，不够。

因此需要 $11$ 罐。

所以正确答案是 E。

Since $\dfrac{128}{12} = 10\dfrac{2}{3},$ ten cans hold only $120$ ounces, which is not enough.

Therefore $11$ cans are needed.

Thus, the correct answer is E.
