Question (2 Marks)
The set of natural numbers $\mathbb{N})$ and the set of integer numbers $(\mathbb{Z})$ are represented in the Venn diagram below.
Label the Venn diagram by placing the draggable numbers provided into the correct location.
▶️Answer/Explanation
Ans:
In the Venn diagram representing the sets of natural numbers ($\mathbb{N}$) and integer numbers ($\mathbb{Z}$), we can place the draggable numbers in the following locations:
$\bullet$ $\sqrt{49}$: This represents the square root of 49, which is 7. We can place the number 7 inside the region that represents the set of natural numbers ($\mathbb{N}$).
$\bullet$ $\frac{12}{3}$: This represents the fraction 12 divided by 3, which is 4. We can also place the number 4 inside the region that represents the set of natural numbers ($\mathbb{N}$).
$\bullet$ 0: Zero is an integer but not a natural number. We can place the number 0 on the border between the regions representing natural numbers ($\mathbb{N}$) and integers ($\mathbb{Z}$) to indicate that it belongs to the set of integers but not the set of natural numbers.
$\bullet$ $-\sqrt{9}$: This represents the negative square root of 9, which is -3. We can place the number -3 inside the region that represents the set of integers ($\mathbb{Z}$).
Here is how the draggable numbers should be placed in the Venn diagram:
