Convert 0.36 to a fraction in simplest form.

• A. 36/100
• B. 9/25
• C. 3/10
• D. 18/50

Answer: (B)

The key idea is turning a decimal into a fraction and then simplifying. 0.36 means 36 hundredths, so it can be written as 36/100. To reduce, find a common factor of 36 and 100; both are divisible by 4, giving 9/25. Since 9 and 25 have no common factors other than 1, 9/25 is already in simplest form. This fraction equals 0.36. Other representations like 36/100 are the unreduced form, and 18/50 is the same value but not simplified, while 3/10 equals 0.3, not 0.36.
