Which term is defined as Any number that isn't a decimal or fraction?

• A. Whole number
• B. Integer
• C. Rational
• D. Natural number

Answer: (A)

A number with no decimal point and no fractional part is a whole number. This means it’s a complete count: 0, 1, 2, 3, and so on. Decimals show parts of a whole, like 3.5, and fractions express parts as a ratio, like 2/3. Since a whole number has no parts beyond the single whole unit, it fits the description of “any number that isn’t a decimal or fraction.” In early math, whole numbers are the non-negative integers, which includes zero, while natural numbers are the counting numbers starting at 1. So the term that matches the idea of numbers without any fractional part is the whole numbers.
