Question

Write 0.4% as a fraction in simplest form.

Answer 1

To find the decimal form of a percentage, you divide by 100.  If you have a decimal, then to divide by 100 just move the decimal 2 places to the left.

0.4% = .004

Now to turn it into a fraction, just read the place value...
four one thousandths = 4/1000

Now reduce... 4/1000 = 2/500 = 1/250

The simplest form of 0.4% as a fraction is...    1/250
