Ants have 6 legs. Elena and Andre write equations showing the proportional relationship between the number of ants, a, to the number of ant legs L. Elena writes a = 6L and Andre writes L=\frac{1}{6}*a

Do you agree with either of the equations?

Lin has a scale model of a modern train. The model is created at a scale of 1 to 48.

On the scale model, the distance between the wheels on the left and the wheels on the right is 1\frac{1}{4} inches. The state of Wyoming has old railroad tracks that are 4.5 feet apart. Can the modern train travel on those tracks?
