OnesTenthsHundredths
025

The last digit is in the hundredths column, so 0.25 is 25 hundredths: 25/100.

Simplify by dividing the top and bottom by the same number. In one go, divide by the highest common factor, 25: 25/100 = 1/4.

If you cannot spot 25, smaller steps get there too:

  1. Divide by 5: 5/20
  2. Divide by 5: 1/4

1 and 4 share no factor except 1, so 1/4 is the simplest form.

As a percentage, 0.25 = 25%: multiply by 100, which moves each digit two places to the left.

To check, divide back: see 1/4 as a decimal and 1/4 as a percentage.
