20	Adding Fractions With Different Denominators For fractions to be added, they must have a common denominator. The common denominator will be the least common multiple of the denominators.
21	Review of Multiples Multiples of a number are found by multiplying the number times one, two, three, and so on. A number that is a multiple of two or more numbers is called a common multiple. The least common multiple is the smallest whole number that is a multiple of two or more numbers.
22	Here is a list of some of the multiples of 3 and 4. Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, … Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, … Common multiples of 3 and 4 include 12, 24, 36, … The least common multiple is 12 because it is the smallest number that is a multiple of both 3 and 4.
23	Add these fractions. The denominators are different, so a common denominator must be found. To find the common denominator, find the multiples of each denominator.
24	Adding Fractions With Different Denominators Compare the lists of multiples, and find the least common multiple. The least common multiple will also be the least common denominator.
25	Adding Fractions With Different Denominators Because 20 is the least common denominator, rename 1/4 and 1/10 as fractions with denominators of 20.

41	Simplify your answer by changing the improper fraction to a mixed number.
42	Review of Mixed Numbers Mixed numbers are whole numbers and fractions together.
43	Adding Mixed Numbers When adding mixed numbers with different denominators, a common denominator must be found. To find a common denominator, find the multiples of each denominator.
44	Adding Mixed Numbers Compare the lists of multiples, and find the least common multiple. The least common multiple will also be the least common denominator.
45	Adding Mixed Numbers Because 20 is the least common denominator, rename 1/4 and 1/10 as fractions with denominators of 20.
