To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.

or

Perform the multiplication as you would for whole numbers.

When you're done, count the number of digits to the right of the decimal point in each factor and add the result.

Place the decimal point in your answer so that your answer has the same number of digits after the decimal point.

If sammmy has 5 alligators biting and each have 100 hunred teeth how many bite marks would he have?
posledela
Hello!

We are given that each of the 5 alligators has 100 teeth. We can use the following equation to find the total number of teeth and, by extension, the total number of bite marks:

(100 teeth) × (5 alligators) = 500 teeth

We have now proven that the 5 alligators have a combined total of 500 teeth. Consequently, Sammy will have 500 bite marks.

I hope this helps!
