When we talk about whole numbers and decimal numbers in Year 7 math, it's important to understand how they work together during math operations.
Whole numbers are the numbers we use for counting. They include 0, 1, 2, 3, and so on.
Decimal numbers, on the other hand, have a point in them. For example, 0.5 and 2.75 are decimal numbers.
Let’s look at how these two types of numbers interact with each other!
When you add a whole number to a decimal number, you line them up like regular addition.
For example, if you have 5 + 2.3, you can write it like this:
5.0
+ 2.3
------
7.3
The same rules apply when you subtract. If you have 7 - 2.5, it looks like this:
7.0
- 2.5
------
4.5
When you multiply a whole number by a decimal number, just treat the whole number like you usually do.
If you multiply 4 by 0.75, it works out like this:
4 × 0.75 = 3
In this case, your answer is a decimal, which is pretty cool!
Division can be a bit trickier, especially if you’re dividing a whole number by a decimal.
For example, if you have 5 ÷ 0.5, you can change it to:
5 ÷ 0.5 = 5 × 2 = 10
So knowing how to change that into an easier calculation is really helpful!
In summary, understanding how whole numbers and decimal numbers work together makes math much easier! Just remember to watch those decimal points and line everything up correctly.
