What is the decimal form of 3/2?

• A. 1.5
• B. 0.75
• C. 2.0
• D. 1.25

Answer: (A)

Dividing the numerator by the denominator converts a fraction to a decimal. For 3/2, ask how many times 2 goes into 3. It goes once, with a remainder of 1. Bringing down a zero to continue, 10 divided by 2 is 5, so the decimal part is .5. Together you get 1.5. It’s also handy to see it as 3/2 = 1 + 1/2 = 1 + 0.5 = 1.5. The other decimals correspond to different fractions: 0.75 is 3/4, 2.0 is 2, and 1.25 is 5/4, not 3/2.
