Question 2

2.

One rectangle measures 2 units by 7 units. A second rectangle measures 11 units by 37 units. Are these two figures scaled versions of each other? If so, find the scale factor. If not, briefly explain why.

Question 3

3.

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 = 6 \sdot l and Andre writes l = \frac{1}{6} \sdot a. Do you agree with either of the equations? Explain your reasoning.
