Sharing is everywhere — food, toys, or books! When you share with numbers, it’s called division. Dive in to discover more about division expressions and symbols!
Imagine you and your friend have a delicious pizza.
So, you slice it up to share! Each slice is like a piece of the whole pizza, and that’s how division works!
Just like you split your pizza into equal parts, division helps you share things fairly.
Keep reading to discover how sharing is not just fun but also a clever way to do math!
Just kidding! It's not your birthday, but you can pretend it is.
Imagine your awesome family made you your favorite kind of cupcakes, and you want to share them with your friends and family.
When you share cupcakes, you're actually dividing them up! You can use division symbols like ÷ or / to show how many you have and how you're sharing them equally.
You have 12 cupcakes, and 3 people want to share them. The division expression can look any of these three ways.
12 | ÷ | 3 | = | 4 | or | 12 | / | 3 | = | 4 | or | 12 | = | 4 | |
3 |
Every way reads, "Twelve divided by three equals four."
If you draw it out, it looks like this.
o o o o | o o o o | o o o o
Here, you see three groups, with four cupcakes in each. So, each person gets four cupcakes!
That sounds like a lot for one person, but maybe your guests will take some home to share, too!
Now, think about 20 marbles.
You want to share them with your one friend. So, the division expression would look like this.
20 | ÷ | 2 | = | 10 | or | 20 | / | 2 | = | 10 | or | 20 | = | 10 | |
2 |
Each of you gets 10 marbles. You could also think of it like this: 2 goes into 20 ten times. If you switch it around like that, it looks like this.
20 ÷ 10 = 2
Now, each of the 10 people would only get 2 marbles.
20 ÷ 4 = 5
Now, each person gets 5 marbles.
Just a heads-up: You can’t divide by zero. That’s right—it’s impossible in math! So if you see a number divided by zero, it's not just wrong—it's completely off the charts!
