See a solution process below:

Explanation:

"Percent" or "%" means "out of 100" or "per 100", Therefore 0.5% can be written as #0.5/100#.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the number we are looking for "n".

Putting this altogether we can write this equation and solve for #n# while keeping the equation balanced:

#n = 0.5/100 xx 490#

#n = 245/100#

#n = 2.45#

#2.45#

Explanation:

First, convert 0.5% into a decimal. To do this, move the decimal point left 2 places.

#0.5% = 0.005#

In math, "of" basically means to multiply. You can rewrite this as
#0.005 * 490#, which is #2.45#.
