Decimal results can be rounded to 0-8 decimal places. If you need to get results in whole numbers, just press 0 - for decimal places and ‘-‘ for fractions.
The app shows you the step-by-step explanation of your problem, including finding the LCM for denominators and reducing the result to lowest terms.
