A 30-inch tall model building was also used in the movie. First, write the proportion, using a letter to stand for the missing term.

We find the cross products by multiplying 20 times x, and 50 times 30. Study this step closely, because this is a technique we will use often in algebra.

Here is the solution: And the ratio 2: is the same as 1:2:6 (because they show the same relative sizes) So the answer is: add 2 buckets of Cement and 4 buckets of Sand.

Sam tried using a ladder, tape measure, ropes and various other things, but still couldn't work out how tall the tree was. That is OK, you simply have twice as many stones as the number in the ratio ...

so you need twice as much of everything to keep the ratio.

We can divide both sides of the equation by the same number, without changing the meaning of the equation.

When we divide both sides by 20, we find that the building will appear to be 75 feet tall.

We are trying to get our unknown number, x, on the left side of the equation, all by itself.

Since x is multiplied by 20, we can use the "inverse" of multiplying, which is dividing, to get rid of the 20.
