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.

2/5 + 1/3 = 6/15 + 5/15 (15 is the lowest common denominator)= 11/15

The LCD of 7/8 and 1/3 is 24.

The LCD of 1/3 and 1/9 is 9.

2/5 + 1/3 = 6/15 + 5/15 (equivalent fractions with a common denominator) = 11/15

Answer: Two fifths, one sixth, and then one third.

No. To compare fractions, you can convert them to a common denominator (in this case, fifteenths). You can also use a calculator to convert each fraction to a decimal.

three, because for one third three was the denominator , and for one sixth the denominator was devisable by three.

Find the "common denominator". 2/5 is 6/15. So 1 fifteenth minus 6 fifteenths is minus 5 fifteenths , or minus one third

1/2 = 3/6 1/3 = 2/6 so your common denominator would be 6

11/15Because 2/5=6/15 and 1/3=5/15.To add fractions you need a common denominator and then you add the numerators and make their sum the new numerator over the common denomerator.

One third of three fifths is one fifth.
