How many decimal places are there in 0.375?
Answer and explanation
Correct answer: 3
The governing concept is counting decimal places, meaning the number of digits written to the right of the decimal point. In 0.375, the digits after the decimal point are 3, 7, and 5. There are no other digits to count, so the number of decimal places is 3. Hence option C is correct. A common mistake is to count the zero before the decimal point, but that zero belongs to the whole-number part and is not a decimal place. Option A would fit a number such as 0.3, option B would fit 0.37, and option D would require four digits after the decimal point, such as 0.3750.
