Example Question #439 : Basic Single Variable Algebra
A textbook says that, on average, a moose that is 
Because this is a question about proportions, we know there's going to be one number divided by another number. First, we're going to group our textbook length and height together:
As you can see, we choose to put the length of the moose in the numerator. It doesn't matter if we put it in the numerator or the denominator yet. When we group the height of the visible moose and it's length, we're going to put the length in the numerator because that's what we did for the textbook length:
Had we put the lengths in the denominators, that would have been fine (we just would have had an extra step when solving the problem). Now we set our proportions equal to each other to get a final equation of:
