Do you struggle to work out fractions? Do you need help in understanding how to add, subtract, divide and multiply fractions? Well if you do then this App is for you. Not only does it calculate the answers for you it also comprehensively explains how the answer was arrived at. This is the App to help your children with their homework because it tells you how it was worked out so you can then explain to them. The App explains about the Least Common Denominator, proper and improper fractions, simplifying fractions and other general concepts.
How to use.
Just type in the fraction values into the fields at the top and select whether each fraction is positive or negative. As you enter the values the explanation is automatically generated to show you the answer and how it was worked out.
Use the four calculation buttons (add, subtract, divide and multiply) to select the type of action.
When the answer is calculated it is shown in the answers box and also in the table below. This table has sections that explain how the whole number parts are handled, finding the lowest common denominator, the greatest common factor, how adding, subtracting, dividing and multiplying work and how fractions are simplified.
If the explanation shows only a red error text then you have specified something that is impossible and you will need to change one or more of the numbers you have specified.
