Fraction and division are closely related.
Mathematically they are the same.

So  ÷  is used for fraction too.

Let’s start with a simple example:

You can enter by clicking:

1  ÷  2  +  3  ÷  4

Or by typing:

1 / 2 + 3 / 4

You get:

To see the result in fraction:

Click    for more options.

When you select Fraction, you get:

And you can see it as an improper fraction too:

Before we go further, let’s learn to be lazy.

The ‘Format Options’ has a Simple Mode.

It automatically closes when you click Decimal or Fraction. Give it a try.

Shortcut

If you prefer using keyboard, ⌘ ⁄  is your friend.
It switches between decimal and fraction.

Mixed Fractions

How do we enter ?

Let’s look at how we say it:

and

We use the ‘and’ operator. This is the button:  & 

Time for an example:

Enter:

1&2 / 3 – 1&1 / 4

Result:

Division

By default, Magic Number shows division in fraction style.
It can also show division as  a ÷ b.

To get  ÷,  press / / (i.e. press  /  2 times)

For  54÷3,  enter:  54 / / 3

This technique is useful for divisions with fractions, e.g.

Enter:

2 / 5  / /  7 / 9

Angles in degrees are generally easier to read than radians.

For example:

DEG

In radians the result looks complicated:

RAD

Let’s see how fraction can help:

Beautiful.

Of course we have not forgotten about decimal.

Go to menu:  View > Angle > Unit Options > r x π
Press ⌘ ⁄  to go back to decimal.

Enjoy!
