For the last couple of days, we have been doing Problem 4.1 and 4.2 in our Comparing and Scaling book. They are both about proportions.

Problem 4.1 shows us four ways to write a proportion to solve a problem.

A. This gets us to figure out what they did, how it works, and if it is correct.
B. We get to try some proportions and we have to explain to discover if we understand.
C. They give us proportions to solve and figure out if our theories from B are right.
D. We use proportions to solve sides of similar shapes.

Problem 4.2 is about everyday use of proportions.

A. How many miles burns how many calories?
B. How many miles in how many hours?
D. How many teaspoons for each dog?
E. How long is one side of a similar figure?

By now, we all have a pretty good understanding of proportions and know how to set it up and how to solve it.
