分数百分数除法口算题

英文回答：

To solve division problems involving fractions and

percentages, we need to follow a few steps. Let me explain.

Step 1: Convert the percentage to a fraction. For

example, if we have 75%, we can write it as 75/100 or 3/4.

Step 2: Invert the divisor fraction. This means we need

to flip the fraction we are dividing by. For example, if we

have 1/2, we invert it to get 2/1.

Step 3: Multiply the dividend (the number we are

dividing) by the inverted divisor. For example, if we have

3/4 divided by 2/1, we multiply 3/4 by 2/1, which gives us

(3/4) (2/1) = 6/4.

Step 4: Simplify the resulting fraction, if necessary.

In our example, 6/4 can be simplified to 3/2.

So, the answer to the division problem 3/4 divided by

1/2 is 3/2 or 1 1/2.

Let's try another example. Suppose we have 60% divided

by 25%. We convert 60% to 60/100 or 3/5, and 25% to 25/100

or 1/4. Inverting 1/4 gives us 4/1. Multiplying 3/5 by 4/1

gives us (3/5) (4/1) = 12/5. This fraction cannot be

simplified further, so the answer is 12/5.

要解决涉及分数和百分数的除法问题，我们需要按照几个步骤

进行。让我来解释一下。

步骤1，将百分数转换为分数。例如，如果我们有75%，我们可

以将其写为75/100或3/4。

步骤2，倒置除数分数。这意味着我们需要翻转我们要除以的

分数。例如，如果我们有1/2，我们将其倒置得到2/1。

步骤3，将被除数（我们要除以的数）乘以倒置的除数。例如，

如果我们有3/4除以2/1，我们将3/4乘以2/1，得到6/4。

步骤4，如果需要，简化结果分数。在我们的例子中，6/4可以

简化为3/2。

所以，3/4除以1/2的答案是3/2或1 1/2。

让我们再试一个例子。假设我们有60%除以25%。我们将60%转

换为60/100或3/5，将25%转换为25/100或1/4。倒置1/4得到

4/1。将3/5乘以4/1得到(3/5)(4/1)=12/5。这个分数不能再简化，

所以答案是12/5。
