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.
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%
Number to a multiple by a positive power of 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).
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.
If we are moving from a large value to a small value we move the decimal point to the 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.
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%
Moving from a smaller value to a larger value.
Number to a multiple by a positive power of 10.
To change a decimal value in to a percentage you have to multiply by 100. This is the same as moving the decimal point two places to the right. So, 4.4 becomes 440%.
