When adding or subtracting fractions with different denominators, it is necessary to find a common denominator to solve the equation. A common denominator is like a common multiple, except its function is as the bottom number in a fraction.

multipy the whole number by the denometer, then add that number to your numerator. now that is your numerator and your denomater stays the same.
wat yhuh do is multipy 2 by 1 and add 4 and put the denometer back at the bottom and your answer is 6-2ex. 41 -2
OK, SO divied 15 by 45. ___ ___ 15 over 45 equals 0.333 with the threes recurring. I got this because 15/45 reduces to 1/3 and 1 divided by 3 is 0.333 with the threes recurring.. The line in between the numerator (the number on the top) and the denometer (the number on the bottom) means "divide", so 1/2 is really 0.5 because 1 divided by 2 is 0.5 Hope this helps
