### Fraction calculation

On a Casio calculator you can enter a fraction with the key

##### Example 1 3 a b/c 1 a b/c 4 + 1 a b/c 2 a b/c 3 = 3┘1┘4+1┘2┘3        4┘11┘12.

##### Example 2  2 a b/c 4 = 2┘4               1┘2. a b/c 2┘4                0.5

##### Example 3 1 a b/c 2 + 1   ·   6 = 1┘2+1.6                2.1

Results of calculations that mix fraction and decimal values are always decimal.

##### Example 4 1 a b/c 2 + 1 a b/c 3 = 1┘2+1┘3               5┘6.

##### Example 5  1 a b/c 9 = 1┘9               1┘9. × 9 = Ans×9                  1.

##### Example 6

To calculate 1 / 2 = 0.5  1 a b/c 2 = 1┘2               1┘2. a b/c 1┘2                0.5

and convert it back again a b/c 1┘2               1┘2.

##### Example 7

Convert the mixed fraction into the decimal fraction 1.5  1 a b/c 1 a b/c 2 = 1┘1┘2            1┘1┘2. a b/c 1┘1┘2                1.5

##### Example 8

Convert the decimal fraction 1.25 into the mixed fraction and in the improper fraction 5/4    1   ·   2   5 = a b/c 1.25           1┘1┘4. a b/c 1.25              5┘4.

##### Example 9

To calculate 2 1/2 = 5/2 = 2.5    2 a b/c 1 a b/c 2 = a b/c 2┘1┘2              5┘2. a b/c 2┘1┘2                2.5

##### Example 10

To calculate 5 8/3 = 7 2/3 5 a b/c 8 a b/c 3 = 5┘8┘3           7┘2┘3.
