Fraction calculations

•Precision set to 1:

•Precision set to 2:

•Precision set to 3:

•Precision set to 4

When entering fractions:

•You use the key to separate the numerator part and the denominator part of the fraction.

•To enter a mixed fraction, for example, 11/2 , you enter it in the format (1+1/2).

For example, to perform the following calculation: 3(23/4 + 57/8)

1.Set the Number format mode to Fraction and specify a precision value of 4. Select Fraction
