Come with me on a journey of division.
I have here a bag of M&Ms, which you and I and two of your friends want to share equally. I'm going to pour the bag out on the table and split it into four equal piles. For this example, “one bag” is our whole, and the best number to represent that whole would
be the number of M&Ms in the bag. Let's say there were 32. If I split those 32 M&Ms...
Division with Decimals
Another type of division you’ll encounter is division with decimals in both the divisor and the dividend. It might look something like this:
In this situation, you move the decimal place the number of spaces in the divisor until the decimal is at the end of the number; you move the decimal the same number of spaces in the dividend: this does NOT necessarily...
Dividing by 10, 100, and 1,000
Dividing by 10, 100, and 1,000 can be done using
long division, like we’ve shown, or you can take a quick short cut to make life a little easier. There are several easy steps you can follow to use this short cut. First, start with a problem that looks like this:
Next, count the number of zeroes in the divisor. In this case, the divisor is 10,...
When starting division, you may be given
simple division problems that you can do in your head, using mental math. Those problems would look like this:
You would think to yourself, what number times 9 gives me 27? And your answer would be 3. However, eventually you will encounter bigger division problems that you cannot do using mental math. In these cases, you...
To divide means to split up a large number into smaller groups of numbers. For example, a group of 50 people could be divided into smaller groups of people, such as 5 groups of 10. In order to do basic division, it is very important that you know your multiplication
tables (or times tables).
For example, you might see a problem that looks like this:
