How do you use a calculater on fractions?

Answer 1

Calculators with built-in support for fractions usually have a key labeled something like "a b/c". Let's call this the "fraction" key. You can type in numbers in two different ways:1) For a proper fraction, for example 2/5, you type: 2 fraction 5.

Similarly, for an improper fraction, for example 3/2, you type: 3 fraction 2.

2) For an improper fraction, for example 1 2/7, you type: 1 fraction 2 fraction 7.

You can write any standard operator between two fractions. Here is an example: To add 1/2 + 2/3, you would type:

1 fraction 2 + 2 fraction 3
