what happen when you divide a 3 -digit number by 10
Depends on what the number is.. Usually what happens is you get an answer ;)
wriring in math explain how you can estimate to tell wether 433-147=285 is reasonable
When you divide a 3-digit number by 10, you simply move the decimal point one place to the left. This means that the resulting number will be 10 times smaller than the original number. To illustrate this, let's take a specific 3-digit number, like 456.
To divide 456 by 10, you shift the decimal point one place to the left, resulting in 45.6. This means that 456 divided by 10 is equal to 45.6.
The reason behind this is that dividing by 10 is equivalent to dividing by a single unit in the tens place. Since each place value represents a power of 10, dividing by 10 essentially decreases the value of the number by a factor of 10.
So, to find the result of dividing a 3-digit number by 10, you simply move the decimal point one place to the left.
