UNIT 9: FRACTIONS - REDUCING TO LOWEST TERMS

Sometimes the numerator of a fraction will divide evenly into the denominator. The fraction can be reduced by replacing the numerator with a 1 and dividing the original denominator by the numerator to get a new denominator.

EXAMPLES:
because 4/2 = 2
because 6/2 = 3


Fractions in which the numerator and denominator contain the same factor can also be reduced by removing the common factor from both the numerator and the denominator.

EXAMPLES:
Remove the 3's because they are in both the numerator and the denominator, and you get--> 2/3
Remove the 7's and you get:3/4
The reason you can remove the 7's is because 7/7 = 1, so it is the same as:


Reduce these fractions to their lowest terms:
(I will give you the common factors for the first 3 problems!)

1)
(common factor is 5)
2)
(common factor is 6)


3)
(common factor is 4)
4)


5) 6)


7) 8)


9) 10)


11) 12)
