If your question was, "What percentage is 2 of 7?"

First, type " 2/7 " into the calculator.

Second, multiply by 100 (or just move the decimal to the right 2 places).

2 is about 28.6% of 7.

Here's another example:

"74 is what percent of 30?"

First, type " 74/30 " into the calculator.

Second, multiply by 100.

74 is about 246.7% of 30

A lot of times I can't remember how to do percents so I just have to go back to what "percent" really means. "Cent" means 100. (A century is 100 years. One cent is one hundredth of a dollar.) Percent literally means per 100.

The question is "*2 out of 7 is what out of a hundred*?" In other words, if you had 2 out of 7 people with red hair, how many people would have red hair out of 100? How many people would have red hair *per 100* people?

This is how to set that up:

\(\frac{2}{7} = \frac{x}{100}\)

Then you solve for x. 200/7 is exactly what we had earlier.

I still go back to thinking of percentages like this just because it is the easiest way for me to think of it.

Lol I realize you probably didn't need a one page essay on this but I just thought I'd share all that.
