When you are faced with a proportion problem, you will ALWAYS set up two fractions equal to each other like this . One side of the equals sign represents an object with two properties. The other side of the equals sign represents the other object with the same exact two properties, but of different values. The numerator of both objects must be the same property. The denominator of both objects must be the same property. They will ALWAYS give you 3 out of 4 numbers, and you'll have to figure out the missing number.

Let's take care of the ant. Let him be the left side of the equals sign with his length (or height if he would stand up) in the numerator and the stride length in the denominator. So the left side would be the fraction .

Let the person be the right side of the equals sign. His height would be 1.65 meters. We'll put that on the numerator BECAUSE we put the ants length (height) in the numerator. We don't know how big his stride must be, so we'll say that it's x. The right side would then be .

<---- We'll solve for x. We're going to cross-multiply.

<------ Cross-multiplication done.

<---- So the person's stride would be about 1.091 meters. That's a pretty big stride.
