# How do you find 0.5% of 250?

Mar 7, 2017

$1.25$

#### Explanation:

The % symbol is like a unit of measurement but one that is worth $\frac{1}{100}$

So  0.5% is the same as 0.5xx%->0.5xx1/100=0.5/100

The use of the word 'of' in 0.5% of 250 is the same as multiply.

Although people do not say this it is the same as

2 of apples$\to 2 + 2 \text{ apples"->2xx"apples" ->"2 apples}$
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
0.5% of 250 $\to \frac{0.5}{100} \times 250$

$= 0.5 \times \frac{250}{100}$

$= 0.5 \times 2.5$

But $0.5$ is the same as $\frac{1}{2}$

$= \frac{1}{2} \times 2.5 = 1.25$
