5% is 5/100. So you can divide by 100 by moving the decimal point 2 places to the left and then multiply by 5, or you can multiply by 5 first and then move the decimal point. Or you can divide by 2 and move the decimal point 1 place to the left. Either way, I get 9.525.
Move the decimal point, the same number of places as the power of 10. That way ---> to multiply. This way <--- to divide.
Left or right.
If you have a fraction, divide the top by the bottom to get the decimal. If you have a decimal, move the decimal point 2 places that way --> to get the percent. If you have percent, move the decimal point 2 places this way <-- to get the decimal.
If you have a decimal, move the decimal point two places that way ---> to get percent.
Either multiply it by 100, or move the decimal point two places to the right. Whichever way you think of it, you get 62 percent.
1 cm = 10 mm, so multiply by 10. The easiest way to do this is to move the decimal point one place to the right...
Take the number of centimeters, move the decimal point 2 places this way and you have centimeters.
The easy way to multiply a percent is to convert it to a decimal. Remember to go from percent to decimal we move the decimal point two places to the left.80% is .80 - Now take .80 and multiply it by 2000.2000x .80====00000160000======160000Now remember their is two decimal places so we need to move the decimals back in 160000.160000.16000.01600.00
Dividing by 0.1 is the same as multiplying by 10, and the simple way to multiply any whole number by 10 is to add a 0 on the end. If the number to be multiplied is shown with a decimal point, just move the decimal point one place to the left.
Converting from litres to millilitres you move the decimal 3 places to the right as the number is getting 1000 times bigger (multiply by 1000)
