Dividing numbers ending in zeros is a method for simplifying division problems when both the dividend (the number being divided) and the divisor (the number you are dividing by) end in one or more zeros. You can cancel an equal number of zeros from the end of both numbers to make the calculation easier.
This strategy works because you are essentially dividing both numbers by 10, 100, or 1,000, which does not change the answer.
To simplify, count the number of zeros at the end of both the dividend and the divisor. Cancel the same number of zeros from the end of both numbers before dividing.
You can only cancel zeros when both numbers end in them. Always cancel an equal number from both.
In word problems, you first need to identify the numbers involved and set up the division equation. Then, you can apply the zero-canceling strategy to find the solution efficiently.
Always read the word problem carefully to ensure you are dividing the correct numbers in the correct order.
This strategy makes mental math and long division much faster and less prone to error by working with smaller, more manageable numbers.
This is not a trick; it is a valid mathematical property based on place value. The quotient (answer) remains the same.
