Simplify 0.50 to its simplest fraction.

• A. 1/2
• B. 5/10
• C. 50/100
• D. 25/50

Answer: (A)

When a decimal has two digits after the decimal point, it can be written as a fraction with denominator 100. So 0.50 is 50/100. Both numerator and denominator divide by 50, giving 1/2, which is in simplest terms. So 0.50 simplifies to 1/2. (Equivalently, 0.50 = 0.5, and 0.5 = 5/10 = 1/2.)
