You are probably familiar with a times table; you know, 2 x 2 = 4, 12 x 12 = 144, stuff like that. But what about 8 x 1-7/8 and crazy stuff like that? Learn how to multiply and bake at the same time!

How do squirrels feel when you hide their food?
By now, you know that when calculating an answer to a math problem, the word "product" means you need to use the operation of multiplication to solve the problem.
This lesson is a chance for you to sharpen your multiplication skills — specifically, multiplying whole numbers with fractions.
Refresh your memory!
Look at the example below to remind yourself of the steps involved in calculating the product of a fraction and a whole number.
Assume that you are asked to solve the problem below:
| 4 | x | 2 | = | |||||
| 3 |
Step 1 Change the whole number into a fraction (It is as simple as putting a fraction line and the number 1 under the number 4.):
| 4 | x | 2 | = | |||||
| 1 | 3 |
Step 2 Follow the rules for multiplying fractions (Find the product for the numerator by multiplying the numerators together and find the production for the denominator by multiplying the denominators together.):
| 4 | x | 2 | = | 8 | ||||
| 1 | 3 | 3 |
Step 3 Change an improper fraction to a mixed number (if needed):
| 4 | x | 2 | = | 8 | = | 2 | 2 | |
| 1 | 3 | 3 | 3 |
Practice makes perfect!
