$1.25$ $1.25$

Explanation:

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

So $0.5 %$ $0.5%$ is the same as $0.5 \times % \to 0.5 \times \frac{1}{100} = \frac{0.5}{100}$ $0.5xx%->0.5xx1/100=0.5/100$

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 $\to 2 + 2 apples \to 2 \times apples \to 2 apples$ $->2+2" apples"->2xx"apples" ->"2 apples"$
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
0.5% of 250 $\to \frac{0.5}{100} \times 250$ $->0.5/100xx250$

$= 0.5 \times \frac{250}{100}$ $=0.5xx250/100$

$= 0.5 \times 2.5$ $=0.5xx2.5$

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

$= \frac{1}{2} \times 2.5 = 1.25$ $=1/2xx2.5 = 1.25$
