Convert 0.25 to a fraction.

Convert 0.25 to a fraction.

• A. 3/16
• B. 1/2
• C. 2/7
• D. 1/4

Answer: (D)

Converting a decimal to a fraction uses the place-value idea. Because 0.25 has two digits after the decimal, it equals 25 over 100. Both top and bottom share a common factor of 25, so you can divide by 25 to simplify: 25 ÷ 25 is 1 and 100 ÷ 25 is 4, giving 1/4. You can verify by turning 1/4 back into a decimal, which yields 0.25 exactly. For reference, 3/16 is 0.1875, 1/2 is 0.5, and 2/7 is about 0.2857, none of which match 0.25.
