Question

A student used the proportion n/100 = 5/26 to find 5% of 26. What did the student do wrong?​

Answer 1

Given:

A student used the proportion
`(n)/(100)=(5)/(26)` to find 5% of 26.

To find:

The student's mistake.

Solution:

Let 5% of 26 be n. Then,

`n=(5)/(100)* 26`

On dividing both sides by 26, we get

`(n)/(26)=(5)/(100)`

So, the proportion used by the student was incorrect. The denominators of the proportion are interchanged.
