Question

1. which set(s) of numbers does -87 belong to? choose all that apply.

□ natural numbers
□ whole numbers
□ integers
□ rational numbers
□ irrational numbers

Explanation:

• Natural numbers are positive counting numbers (1,2,3,...), so -87 is not in this set.
• Whole numbers are non-negative integers (0,1,2,...), so -87 is not in this set.
• Integers include all positive and negative whole numbers and 0, so -87 is an integer.
• Rational numbers are numbers that can be written as $\frac{a}{b}$ where $a,b$ are integers and $b

eq0$. Since $-87 = \frac{-87}{1}$, it is rational.

• Irrational numbers cannot be written as a fraction of two integers, so -87 is not irrational.

Answer:

□ Natural numbers
□ Whole numbers
☑ Integers
☑ Rational Numbers
□ Irrational Numbers
