D. Using a previous question to build a new question

Step 1: Think about the construction of problem 2 in our Quiz.

The number 415 is 83% of what number? (Answer 500)

How does this problem differ from problem 1?

Thinking: a. The Variables are the same and the Relationships are the same.

b. The Conditions are the same.

c. Only the order of the words is different. For example, we now have:

"The number b is p% of a."

So we can use all of our Algorithm Definitions from question 1 and just change the question and the answer. How do we do this?

We duplicate question 1.

Step 2: Duplicate question 1.

Click (once) on question 1. Then, the background of this question should be yellow.

Now select the Question menu, then Duplicate

or press [Ctrl] + [D] (press and hold the Ctrl key and then press d).

Note: EVTG uses the shortcut [Ctrl] + [D] to duplicate questions in page mode (what we just did) and [Ctrl] + [D] to open the Algorithm Definitions in question mode (see Part C, Step 2 above). If you accidentally get these mixed up and duplicate a question, see Chapter 3, Part G: Troubleshooting.

A new question will appear. Note that new values are automatically generated, and remember your values will likely be different!

This new question is now active, i.e. its background will be yellow and when we click on the Edit button at the bottom, we will be working on this question.

Step 3: Edit question 2.

We now wish to make question 2 look like our problem 2, so we need to edit this question.

Click on Edit (bottom left) or double-click anywhere on question 2.

The question page will open.

Follow the instructions below.

Finish the question. (You can erase "What..." and use the variable p or type everything over and insert the variable p again by selecting the Insert menu and selecting Variable.) Remember, it must have the shaded background or it is not a variable!
Click in the answer section, erase the variable b and insert the variable a(see below).

Click on Record at the bottom of this page to save the question.

We have a new dynamic question! (Your numbers will be different.)

Try changing the values of this question by clicking on the Calculate Values button .

Save your file by selecting the File menu, then Save,

or click on the button on the toolbar,

or press [Ctrl]+[S]( press and hold the Ctrl key and then press S).

We now know all the steps we need to make our third problem.

What percent of 135 is 27? (Answer 20%)

See if you can think the steps out by yourself before you read on!
