How do you convert a percent into a ratio?

Answer 1

Here is a simple method to do this. If you are a mathematician, I apologize because this is worded in a way to make it easy to do and understand for people who are not good at or do not like math. It is not mathematically precise at all. Let's look at 10%, that is the same as .1 and 2% is the same as .02. That is how we convert percents to decimal. We simply imagine their is a decimal point on the right side of the percent. For example 10 is 10. and then move that to the left 2. so 10 become .10 and 2 is 2. so it becomes .02 since we need to put in a zero to move it to the left 2 positions. Now 30% becomes .30 or just .3 but 300% become 300. and when we move the decimal it is 3.00 or just 3 This is because percents are all parts of 100. Now .1 is 1 tenth so the ratio is just 1/10 and.02 is 2 hundreds so the ratio is 2/100 and 3 is 3/1 or 300/100 Why this works: 10% is defined as 10/100 ( but this reduces to 1/10) 2% is defined as 2/100 300% is defined as 300/100 that is the way percents are defined. The word percent means part of a hundred.
