Look on your task bar. You should see "Microsoft Excel - Book 1" as one of the choices. Multitasking will require you to switch back and forth between files.

You could try resizing the windows so that you can view both applications at the same time. Or you can read this one then click "Microsoft Excel" on the task bar to complete your assignments.

Today we will be using Microsoft Excel to solve proportions.
You will use workbook page 8.2 for the proportions. Get your workbook or print a copy of the page now.

The first problem is ¹⁸/₃₃ = ⁿ/₁₁.
Let's type this problem into Excel so that it will be easy to see.
In cell A1 type 18
In cell A2 type 33
In cell B1 type n
In cell B2 type 11

Let's make it look pretty so that we will better be able to see what it says.
Highlight all the cells A1:B2.
Select "Format" from the menu bar.
Select "Cells"
Select the "Alignment" tab
Use the drop down arrow next to "Horizontal" to change the horizontal alignment to centered.
Select "OK" to apply the changes.

Now - We don't need that to solve the problem - we only made it to help us visualize the proportion. Let's solve the problem.
Multiply on the cross is 11 * 18
then divide by the remaining number (33). We will put the cross products in cells A4 and B4 then put the divisor in cell C4.
Use the tab key to move horizontally in Excel.
In cell A4 type 11
In cell B4 type 18
In cell C4 type 33

To calculate the value of n, we will put the formula =A4*B4/C4 into cell D4.
Type or paste the formula into cell D4 and press enter. What is the value of n?

The cross product in problem two is 26 * 3. Then we will divide by 2.
Use the tab key to move horizontally in Excel.
In cell A4 type 26
In cell B4 type 3
In cell C4 type 2
Press enter to force cell D4 to calculate.
What is the value of n?

Problem 3 has cross products 5 * 8 divided by 10.
Use the tab key to move horizontally in Excel.
In cell A4 type 5
In cell B4 type 8
In cell C4 type 10
Press enter to force cell D4 to calculate.
What is the value of n?

As you can see - you will be able to finish your assignment very quickly and easily using these cells and the formula in cell D4.
You can use the proportion you made to help you see the proportion for the word problems (12 and 13). Good Luck and enjoy your new skill!
