First let's think about a simpler problem: Find 3/4 of 20 .

We want to take 20 , divide it into 4 parts of equal amount, and take 3 of them.

20/4 = 5 ( Think... 5 + 5 + 5 + 5 = 20 )

So... one fourth of 20 is 5 . Three fourths of 20 is 3 * 5 , or 15 .

3/4 of 20 = 3 * 20/4 = 3 * 5 = 15

Using the same logic.... we can find 21/25 of $27,000 .

21/25 of $27,000 = 21 * $27,000/25 = 21 * $1080 = $22,680

A new law requires that 12% of an individual's income be invested in the stock market. Your accounts show that you need to put $420 in the stock market this year. How much did you earn this year.

12% of your income = amount you need to put in the stock market

12% of your income = $420

12/100 of your income = $420

12/100 * your income = $420

0.12 * your income = $420 Divide both sides of this equation by 0.12 .

your income = $420 / 0.12

your income = $3500
