I don't know fraction

Step-by-step explanation:Fractions are a part of a whole for example if you have a circle and cut it in 4. Then you take out one cut of the 4 cuts on the circle. Then the remaining circle is ¾.If you're talking about addition of fractions the use this: For example ¾+⅖. Take the lowest common multiple of 4 and 5 (the denominator of the fractions) (denominator is the under part of a fraction and numerator is the upper part).LCM (LOWEST COMMON MULTIPLE) of 4 and 5 is 20, (because 20 can divide both 4 and 5)
