Question

How do you find 0.5% of 250?

Answer 1

`1.25`

Explanation:

1) Convert that percentage to either fraction or decimal:
`0.5% = 0.005`

2) Simply multiply your result by the total number
which in this case is 250:
`0.005 xx 250 = 1.25`

3) Therefore `5% "of " 250 = 1.25.`

OR

The way I always try to do it (which can be a real challenge and you can do it even in your head if you practise a little) is:

I simply look at the total number, which is 250, and think

"what is 1% of that number?" (which is same as dividing by 100).

In this case it is `2.5` because `250/100 = 2.5`

We know that the question is asking for `0.5%`and NOT `1%.`

It should be easy enough to know `0.5` is half of `1`.
So you just divide the answer of `2.5 " by " 2`.

`2.5/2 = 1.25`

As you can see it is the same number as in the first method.

Word of caution: This method will get more difficult if the numbers aren't so easy and straight forward. So for example if it asked for 43% of 250, then I encourage you to follow the first method.

Hope this helped (c:
