what type of number is $-\frac{15}{3}$? choose all answers that apply: a whole number b integer c rational d…

Explanation:

Step1: Simplify the fraction

$-\frac{15}{3}=- 5$

Step2: Recall number - type definitions

Whole numbers are non - negative integers (0, 1, 2, 3, ...). Since - 5 is negative, it is not a whole number. Integers include positive and negative whole numbers and zero. So, - 5 is an integer. Rational numbers are numbers that can be written as a fraction $\frac{a}{b}$ where $a$ and $b$ are integers and $b\neq0$. Since $-5=\frac{-5}{1}$, it is a rational number. Irrational numbers cannot be written as a fraction of two integers. Since - 5 is a rational number, it is not irrational.

Answer:

B. Integer, C. Rational
