Addition. Reduce when necessary. Change all improper fractions to mixed numbers.
Remember: If denominators are the same:
1) Add the numerators for the numerator of the answer
2) The common denominator is the denominator of the answer
Example: 7 + 9 = 7 + 9 = 16 = 1 7/9
9 9 9 9
61. 7 + 9 62. 31 + 22 63. 57 + 29

Subtraction. Reduce when necessary. Change all improper fractions to mixed #'s.
Remember: If the denominators are the same
1) Subtract the numerators for the numerator of the answer
2) The common denominator is the denominator of the answer
Example: 13 - 7 = 13 - 7 = 6 = 1
12 12 12 12 2

16 16 9 9 109 109
Multiplication. Reduce when necessary. Change all improper fractions to mixed #'s.
Remember: 1) Multiply the numerators for the numerator of the answer
2) Multiply the denominators for the denominator of the answer
Example: 9 ( 5 = ( 9 )( 5 ) = 45 = 3 3/14
2 7 ( 2 )( 7 ) 14

5 7 3 9 9 5
Division. Reduce when necessary. Change all improper fractions to mixed #'s.
Remember: 1) Invert the divisor (That means flip the second number over) and
multiply.
2) Multiply the numerators for the numerator of the answer
3) Multiply the denominator for the denominator of the answer
Example: 3 ( 5 = 3 ( 7 = ( 3 )( 7 ) = 21 = 3 ( 7 = 7
9 7 9 5 ( 9 ) ( 5 ) 45 3 (15 15
