Homework Help: Pre-Algebra

Posted by Joel on Monday, January 24, 2011 at 6:22pm.

If 4 liters of motor oil cost $3.88, what is the price for 1 liter? I'm supposed yo set up proportions. This is how I set it up:

$3.88/4 liters • 1 liter/p
p= the price for 1 liter

Please tell me if I set it up right and how to solve.

You're close. But you need the price as the numerator and the gallons as the denominator.

3.88/4 = p/1

Cross multiply.

4p = 3.88
p = 3.88 / 4
p = ?
