12, i think

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.

Find the common denominator then make it into improper faction and subtract

The LCD of 3/16 and 1/3 is 48.

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

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

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

yes. When you are working with fractions like this, the smaller the denominator, the larger the fraction.

yes it is, the smaller the denominator the bigger it is.

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

To add one third and one half, you'll want a common denominator. In this case, it's 6.

1/3+1/4 In order to solve a math problem with different denominators(the bottom digit of a fraction) you first must change both fractions to have the same denominator. In order to find the same denominator, you must find what is known as the least common multiple of each denominator. The least common multiple of 3 and 4 is twelve. So you must multiply each fraction to get the denominator the same. 4/12+3/12= 7/12

5/6 In order to solve you need a common denominator. This would be the LCD (least common denominator. The LCD in this case is 6. Multiply the top and bottom of the fraction by the same number to get the LCD on the denominator. 1/2 + 1/3 becomes 3/6 + 2/6=5/6
