False. Explanation: As rational numbers are of the form $\frac{\text{p}}{\text{q}}$ where $\text{q}\neq0.$ Whole numbers are natural numbers together with a zero. For example, $\frac{5}{7}$ is a rational number but not a whole number.
False. Explanation: As rational numbers are of the form $\frac{\text{p}}{\text{q}}$ where $\text{q}\neq0.$ Integers are negative and positive numbers which are not in $\frac{\text{p}}{\text{q}}$ form. For example, $\frac{1}{2}$ is a rational number but not an integer.
True. Explanation: As rational numbers are of the form $\frac{\text{p}}{\text{q}}$ where $\text{q}\neq0.$ All integers can be represented in the form $\frac{\text{p}}{\text{q}}$ where $\text{q}\neq0.$
True. Explanation: since natural numbers are counting numbers i.e N = 1, 2,... Whole numbers are natural numbers together with 0. i.e W = 0, 1, 2,... So, every natural number is a whole number.
