Is anyone familiar with this formula for figuring out percent? How it would work?

p/100 = of/is

I was going to say I don't know what the of/is means

If p is the percentage, dividing it by 100 gives you the equivalent fraction. That may be what your teacher is probably trying to say with that formula.

Thanks.

Yes, the formula you mentioned is often used to calculate percentages. This formula relates the part-to-whole relationship and can be used to find the value of a percentage.

Let's break down the formula:

- "p" represents the percentage you want to find.
- "of" represents the value or quantity you want to calculate the percentage of.
- "is" represents the total value or quantity.

To use this formula, follow these steps:

1. Identify the values: Determine the value of "of" and "is" in the given problem.
2. Substitute the values: Replace the corresponding letters in the formula with the respective values.
3. Solve for "p": Rearrange the formula to isolate "p" (the percentage you want to find). This can be done by cross-multiplying:
- Multiply "p" and "is" together.
- Divide the result by "of".

Mathematically, the calculation would look like this:

p/100 = of/is

To solve for "p", cross-multiply and then divide:

p * is = 100 * of

p = (100 * of) / is

This formula allows you to find the percentage value you're looking for by comparing the part ("of") to the whole ("is").
