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.

∙ 10y agomultipy 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
Well you have to simplify which means to see what the num. that goes into both nums. witch in this case is 2. 2 into 4 is 2 so 2s your numerator (top) and 2 goes into 18 9 times so the denometer (bottom) is 9. Remember what num. goes in the 2 nums. evenly (it has to be the same num. for both) divide it thensee if it can go again . zIf so repeat with these nums.,m and it CAN go twice.
A few synonyms for common denominator are , common divisor, common measure, denominator, numerator

Their product.
Divide both sides by the lowest common denometer which in this case is 2. So 10/12 = 5/6

yes one third is bigger than one ninth... if you multiply the numerato by the numerator and the denominator by the denometer one third is equivalent to 3/9
22 divided by 15 18 divided by 12 whichever number is higher is the answer 22x4=88----18x5=90------you have to find the common denometer which i chose to be 60 (60 minutes in an hour) so 15x4==60 -----and 12x5=60 . ----then you multiply 22x4 ====and 18x5 and dusty is the most productive by 2 items
