Example Question #1 : Multiplying Multi Digit Decimals
Find the product.
Steven bought 4 cheeseburgers to share. Each cheeseburger costs $0.79. How much did Steven pay for the 4 cheeseburgers?
The easiest way to do this problem is to multiply 
Another option is to add 
Either way, the correct answer is 
Example Question #2 : Multiplying Multi Digit Decimals
Multiply:
We ignore the decimals for the time being, multiplying:
Since, between them, the two original factors have a total of two digits to the right of their decimal points, we place the decimal point in the product so that there are two digits to the right. This yields:
Example Question #3 : Multiplying Multi Digit Decimals
Gina is recylcing bottles. She earns 
If Gina recycles 
Multiply the number of plastic bottles Gina recycles by the amount she earns for each plastic bottle, then multiply the number of glass bottles she recycles by the amount she earns for each glass bottle.
Add these earnings together to find Gina's total earnings.
Example Question #1 : Multiplying Multi Digit Decimals
Isaiah buys 5 snacks from the vending machine . If each snack is $1.75, how much money does Isaiah spend?
Since each snack costs $1.75, multiply $1.75 by 5 to find the total cost:
Example Question #1 : Multiplying Multi Digit Decimals
Jenny is getting ready for school. She bought school supplies on a tax-free day. She bought notebooks for $1.25 each and crayons for $0.90 each. Jenny bought two more notebooks than crayons. She paid with a ten dollar bill and got $1.05 in change. How many notebooks did she buy?

5
Define variables as x = number of crayons and x + 2 = number of notebooks
To find out how much she spent, we subtract her change from what she paid with: 10.00 – 1.05 = 8.95
Then we need to solve the problem cost of notebooks plus the cost of crayons equals the total cost.
1.25(x + 2) + 0.90x = 8.95 and solving for x gives 3 crayons and 5 notebooks
Example Question #1 : How To Add And Subtract Decimals
The above is a menu at the concession stand at a drive-in movie. The stand also offers a Family Chicken Strip Bucket - twenty chicken strips, four medium orders of fries, and four medium sodas for $30.
How much more would the items of the Family Chicken Strip Bucket cost if they were purchased separately?
(Ignore tax)
There are twenty chicken strips in the Family Chicken Strip Bucket, which are the same as in five orders; each order costs $3.99 separately. Each medium order of fries costs $2.79 separately, and each medium soda costs $1.69 separately. The items separately cost a total of
Subtract $30; the savings amount to
Example Question #11 : Problem Solving
Multiply:
Multiply the terms as is, ignoring the decimal.
Since there is one decimal from the original problem, the decimal place is one unit from the right. Therefore, the final answer must have a decimal one unit to from the right.
The answer is
