3 - 4-1/2 = 6/2 - 9/2 common denominator would be 2.
2/3 and 3/4 Least Common Denominator is 12
find a common denominator for all three and then add all of the numerators together and keep the same denominator
Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.
20
the least common denominator of three fifths and two fifteenths and one sixth is 30. you multiply 15 by two, 6 by five, and 3 by ten.
Find the common denominator then make it into improper faction and subtract
A common denominator is 32.
if you have a common denominator, the answer will remain the number that the common denominator is. like say the fraction is 3/4-2/4 (three over four minus two over four), the answer would be 1/4 (one over four)
Ten minus five is 5. Now to the fractions, change one fourth to two eighth and u have a common denominator. Now three minus two is 1 so u have an answer of 5 and 1/8.
The common denominator is 4
The least common denominator of three fourths and five sixths is twelve.
three, because for one third three was the denominator , and for one sixth the denominator was devisable by three.
8\12 - 3\32 common denominator: 96 64\96 - 9\96 the answer is 55\96
The lowest common denominator would be twelve!
3/83/4 - 3/8 = 6/8 - 3/8 = 3/8Always find the common denominator first when adding or subtracting fractions.
To calculate three tenths minus one twentieth, first convert both fractions to have a common denominator. The common denominator for 10 and 20 is 20. Thus, three tenths (3/10) can be converted to 6/20. Now, subtract one twentieth (1/20) from six twentieths (6/20): 6/20 - 1/20 = 5/20. Simplifying this fraction gives you one quarter, or 1/4.
90 is your common denominator.
