A fraction can be entered into the worksheet in several different ways. There is no preferred way; it is simply a matter of personal choice. Note that 
has a pull-down arrow that enables you to access other fraction buttons.
Using the fraction character – ‘/’
Example:
Typing a/b will create 
. However, notice that typing ab/c will create 
, which may not be what you wanted. There are several ways to "force" a into the numerator. For example, you could place ab into parentheses: (ab)/c will produce 
.
Using the "New fraction" button
When you click on the 
(New fraction) button, it produces a fraction template 
so that you can fill in both the numerator and the denominator. First enter the numerator, and then either click on the denominator space-holder 
or use the 
key to move "down" and enter the denominator.
Using the "Selected numerator" button
This method is typically used when the numerator is already entered, i.e. you have entered 2x+3 and now you wish to turn it into the numerator of a fraction. Highlight the desired numerator with the mouse (or using the <Shift> key followed by the right or left arrow key), then click on the 
(Selected numerator) button. You will now be able to enter the denominator.
Using the "Selected denominator" button
This is not a very common way of entering a fraction. It assumes that you have already entered the denominator, but not the numerator. For example by entering a+b, selecting it and clicking on the 
(Selected denominator) button you will have created this expression 
. Now you only need to enter the numerator.
Entering Mixed numbers
Clicking on the 
(mixed number) button will create a mixed number template 
.
Enter the whole part and then the numerator and denominator of the fractional part.
How do you "exit" a fraction?
For example, if the cursor is at the end of a denominator and you want to add another fraction to the existing one. Simply press the 
key – the cursor’s size will tell you your exact position within the expression.
