$1.25$

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

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 $->2+2" apples"->2xx"apples" ->"2 apples"$
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
0.5% of 250 $->0.5/100xx250$

$=0.5xx250/100$

$=0.5xx2.5$

But $0.5$ is the same as $1/2$

$=1/2xx2.5 = 1.25$
