Answer:

#1.25#

Explanation:

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#
