How do I work with fractions?
The Frac button only switches the current answer between decimal and fraction format. To insert fractions into your expression, just use the division sign.
For example, assume you want to add together two thirds and one fourth, and view the result as a fraction:
1. The first step is to type 2÷3+1÷4. The result will show 0.91666667
2. You can then tap Frac, and the result will be 11/12
3. You can continue to tap Frac to switch between the two formats.
