How does the decimal point move when you rewrite a percent as a decimal and when you rewrite a decimal as a percent?
It's pretty simple. Every percent is out of 100. There is no possible percent higher than one hundred. So, when a percent needs to be changed into a decimal, you move it 2 decimal points to the left. This is so because percent means parts of 100, where 100 has 2 zeros. For example: 80% is 80/100. 80/100 = .8, so you move the decimal point two times to the left. When you rewrite a decimal as a percent, you do the opposite; move it two decimal points to the right. Make sure that the decimal is not greater than one because one is equal to 100% and as I said before, nothing can be greater than 100%. For example: .9934 = 99.34% or 99.34/100; move the decimal two to the right. I hope that helps.
How do you convert parts per thousand to percent?
Move the decimal point one place to the left. Percent literally means per hundred, so 1 part per thousand is 0.1%, 10 parts per thousand is 1%, 100 parts per thousand is 10%, and 1000 parts per thousand is 100% or a whole.
