Convert 0.125 to a fraction in simplest terms.

• A. 1/8
• B. 1/4
• C. 3/8
• D. 5/16

Answer: (A)

Converting a decimal to a fraction involves using its place value and then simplifying. The decimal 0.125 has three digits after the decimal, so it can be written as 125/1000. Both numbers are divisible by 125, which reduces the fraction to 1/8. Since 1 and 8 have no common factors besides 1, this is in simplest terms. The other options correspond to different decimals (0.25, 0.375, 0.3125), so they don’t match. Therefore, 1/8 is the simplest form.
