Dividing numbers ending in zeros is a mathematical process where both the dividend (number being divided) and/or the divisor (number dividing by) end with one or more zeros. Special strategies make these problems easier to solve.
When numbers end with zeros, we can simplify the division by temporarily removing the zeros and then adding them back to our answer.
When both dividend and divisor end with zeros, you can remove the same number of zeros from both numbers before dividing.
You can only remove zeros when both numbers have zeros to remove. Always remove the same number from both.
When only the dividend ends with zeros, you can still simplify by removing zeros, but you must add them back to your quotient.
When only the dividend has ending zeros, remove them before dividing, then add the same number of zeros to your answer.
When both dividend and divisor end with zeros, remove the same number of zeros from both, divide, and your answer is complete.
When both numbers have zeros, you don't need to add zeros back to your answer because you've already simplified proportionally.
Always verify your division answer by using multiplication. Multiply your quotient by the divisor to see if you get the original dividend.
Multiplication is the inverse operation of division. Using it to check your work helps catch errors.
Recognizing patterns in division with zeros helps you solve problems more quickly and accurately.
