You round
When you divide by ten the decimal point moves one place to the left.
The decimal point moves one place to the left when dividing by 10.
Write the number and move the decimal point to the left 3 digits.
Divide seven by eight. Remember, you will get a number less than one, so place your decimal point.
When you divide a decimal number by a power of ten, the decimal point moves to the left by as many places as the exponent of ten indicates. For example, dividing by 10 moves the decimal point one place left, dividing by 100 moves it two places left, and so on. This pattern effectively reduces the value of the decimal number. Conversely, multiplying by a power of ten moves the decimal point to the right.
a number with a decimal point is a a fraction, a part of the whole goes behind the decimal. where as one with out a decimal point is just a whole number.
Either multiply the number by 1/10 or divide the number by 10 or move the decimal point one position to the left
Take the diameter, then divide by 2 to get the radius. To get to scientific notation, put the number in the form of one digit followed by a decimal point, then the rest of the number, followed by x10n, where n is the number of places that you had to move the decimal point to get just one digit to the left of the decimal point. For example: diameter of 8. Divide by 2 to get 4. To get to scientific notation, make it 4X100. You didn't have to move the decimal point at all, so n=0. Example #2: Diameter of 250. Divide by 2 to get radius, which is 125. To make it scientific notation, you have to move the decimal point 2 places to get 1.25X102. If you had to move the decimal point to the right, then make n a negative number. Example #3: Diameter of 1/10. Divide by 2 to get radius of 1/20, or 0.05, which in scientific notation is 5X10-2.
There is only one decimal point in the number Pi
To divide a number by ten, put a decimal point one place to the left: 14.4
Divide the number by 10: that is equivalent to moving the decimal point one place to the left.
Two ways. Pick the one you prefer.1). Divide the number by 100.2). Move the number's decimal point two places to the left.
