I need help solving a proportion word problem?

:-

egg sub (oz)______cholesterol (mg)

2_____________________45

3_________________3/2 x 45

135/2 = 67•5 mg of cholesterol

There are 45 mg of cholesterol in 2 ounces of egg substitute.

There are 67.5 mg of cholesterol in 3 ounces of egg substitute?

To solve the problem you have to first find out how many mg are in 1 ounce of the egg substitute. Let use "x" to represent that number.

We know this:

2x = 45

We then do the math and find the value of x by dividing both sides by 2

2x/2 = 45/2

x = 22.5

Now that we know how many mg are in 1 ounce, we multiple by 3 to get the number of mg in 3 ozs.

3(22.5) = 67.5

So there are 67.5 oz of cholesterol in 3 oz of egg substitute

1 ounce of egg substitute has 45/2=22.5mg cholesterol

3 ounce of egg substitute has 22.5 x 3 = 67.5mg cholesterol
