Since you can earn 28 dollars by washing 7 cars, and you want to find the amount money you can make by washing 6 cars.
![\frac{28}{7} = \frac{x}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B7%7D%20%3D%20%5Cfrac%7Bx%7D%7B6%7D)
First, you should find the amount of money you can make by washing 1 car (unit rate).
![\frac{28}{7} = \frac{x}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B7%7D%20%3D%20%5Cfrac%7Bx%7D%7B1%7D)
To get from 7 to 1, you have to divide 7 by 7; 7 ÷ 7 = 1.
Do the same thing to the numerator; 28 ÷ 7 = 4.
Now you know how much you make by washing 1 car, you need to find how much you make by washing 6 cars.
![\frac{4}{1} = \frac{x}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B1%7D%20%3D%20%5Cfrac%7Bx%7D%7B6%7D)
To get from 1 to 6, you multiply by 6. 1 times 6 equals 6.
Now do the same thing to the numerator; 4 × 6 = 24.
You can earn 24 dollars by washing 6 cars.
