Share the Skittles!
Hooray! Mom has bought a giant bag of 120 Skittles for you and your friends for movie night! You have to share them with your 9 friends. So, let's figure out how we can divide the candy evenly between 10 people, your 9 friends plus yourself! When you divide the Skittles, each person will have an equal amount to eat! Yummy! So we have to figure out what is 120 divided by 10!
How to Divide the Skittles
- Count the number of total Skittles. We already know that the bag has 120 candies!
- Line up 10 cups. 1 cup for each person! Begin putting 1 Skittle in each cup until each cup has 1. Then, repeat until each cup has 2, 3, 4, etc. When you have no more Skittles or you don't have enough left to give every cup one (for example, you only have 4 left) you are finished dividing.
- How many Skittles are in each cup? This number is the answer, or quotient, to your division problem. If you were to have any left over, that number is called the remainder. So in our case, the quotient is 12 since there were 12 candies in each cup. The remainder is 0 since we do not have any pieces left over!
You just divided 120 by 10! So, 120 ÷ 10 = 12. Or, 120 Skittles divided among 10 people equals 12 Skittles per person. How cool!
Multiplying to Divide
Did you know you could use multiplication to solve a division problem? Let's see how it's done!
You are planning a birthday party! You want each of your friends to have 10 balloons for the balloon popping game. If you already have your 10 balloons and you have 60 more balloons, how many friends can you invite to your party?
- Count the total number of balloons: 60
- Start putting your balloons in piles of 10 each.
- When you have no more balloons left, count the number of groups of 10 you made. This is the number of friends you can invite, since each friend will get a group of 10 balloons.
Here's the division problem: 60 ÷ 10 = 6. You can invite 6 friends!
You just used multiplication to divide! You solved the problem 10 x 6 = 60 by counting by tens until you reached 60, which was your total number of balloons. For more examples of multiplication by 10, see the lesson How to Multiply by 10.
Dividing by Ten Using Mental Math
There's an even easier way to divide by ten - you can use mental math! There's a neat trick that you can use. The only really important thing to note here is that you can only use this method if the dividend ends in a 0! Let's try it!
400 ÷ 10 =
- The 0's on each side cancel each other out! Remember that we can do this because 400 (our dividend) ends in a 0!
- This leaves you with 40 ÷ 1, which you know equals 40. So, 400 ÷ 10 = 40.
Divide means to separate into equal groups or parts. Division by ten can be easy, and there are a few strategies you can use to do it! When you have your answer, that's called a quotient. And if you're dividing and happen to have some left over, that's called a remainder!
