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.

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

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

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

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