Ever wonder how multiplication and division are related? Change some symbols and switch the numbers around, and you will quickly see these families form!
Maybe a sister or brother, cousins, aunts, uncles, grandparents, and don't forget a mom or a dad! You might even have step-parents, second cousins, or great aunties.
Numbers have relatives too. However, their family trees look a lot different.
They are not cousins. Instead, those numbers are related by addition and subtraction operations!
9 + 1 = 10
1 + 9 = 10
10 - 1 = 9
10 - 9 = 1
Numbers can also be related through multiplication and division!
Let's look at the numbers in the multiplication equation below:
Much like in your family, these titles matter and help to describe the relationships.
Factors are numbers that, when multiplied, make up a product. The product is the answer in a multiplication equation.
You can display this multiplication equation with equal groups or an array:
Let's look at the product from the equation.
The product is 6. There were 6 total dots in our equal groups drawing.
In a division equation, the product becomes the dividend. The dividend is the total amount to be divided or split up.
In this case, the total is 6:
The divisor is how many groups the total will be split into. In this case, the dividend will be split into 2 groups:
To find the quotient or the answer of a division equation, you will need to divide the 6 total dots into 2 equal groups. Then, count how many dots are in each group!
Compare this equal group drawing to the one above. They are the same!
There are two more equations that complete this family.
Yes! We use the commutative property of multiplication to find these equations in our fact family.
