Which term means a number that includes a decimal point?

• A. Cube
• B. Percentage
• C. Decimal
• D. Denominator

Answer: (C)

The main idea here is recognizing how we name numbers that include a decimal point. A decimal is a number that has a decimal point separating the whole part from the fractional part, like 3.14 or 0.5. Decimals are used when we need precision beyond whole numbers, common in money and measurements. The other terms describe different concepts: a cube refers to a three-dimensional shape (or to a number raised to the third power), a percentage expresses a part of a hundred, and a denominator is the bottom number of a fraction indicating how many parts the whole is divided into. None of those inherently denote a number with a decimal point the way the term decimal does.
