The magnitude or value of the number.
To change a decimal to a percentage, all you need to do is multiply it by 100. This is the same as moving the decimal point two spaces to the right. .453 = 45.3%
Change % to decimal by dividing it by 100 or by simply moving the decimal point two places to the left. In this case, 30% will be equal to 0.3. Then divide.
Number to a multiple by a positive power of 10.
First, turn the mixed number into a improper fraction. Then change the improper fraction into a decimal. Then, change it into a percent by moving the decimal point two spaces to the right. Ex: .10 is 10%
you change 31 percent into a decimal by moving the decimal point to the left twice ( or divide by 100 then multiply 42 X .31 13.02
To change a decimal to a percentage, all you need to do is multiply it by 100. This is the same as moving the decimal point two spaces to the right. .453 = 45.3%
Change 0.23 to a percent by moving the decimal point 2 places to the RIGHT and add the percent sign. 23%
change the fraction in to a decimal by dividing the numerator by the denominator . Then multiply by 100 (same as moving the decimal point left 2 places).
If we are moving from a large value to a small value we move the decimal point to the left.
Moving the decimal point one place to the right is the same as multiplying both, he numerator and the denominator by 10. That is, you are effectively multiplying by 10/10 which equals 1. And since multiplication by 1 does not change the result, it is OK to do that. Similarly, moving two palces to the right is multiplying by 100/100. Similarly moving left.
Moving from a smaller value to a larger value.
Change % to decimal by dividing it by 100 or by simply moving the decimal point two places to the left. In this case, 30% will be equal to 0.3. Then divide.
Moving from a smaller value to a larger value.
Number to a multiple by a positive power of 10.
To change from one unit to another usually involves multiplying by a power of ten, which is as simple as moving a decimal point. For instance: the prefix "kilo" means a thousand; therefore, to convert from kilometers to meters, you multiply by a thousand, which is equivalent to moving the decimal point three positions to the right.
First, turn the mixed number into a improper fraction. Then change the improper fraction into a decimal. Then, change it into a percent by moving the decimal point two spaces to the right. Ex: .10 is 10%
Move the decimal point one place to the right. If the decimal point is already at the end of the number, add a 0 to the extreme right before moving the decimal point.
