a. A fraction is said to be at its lowest terms when the numerator and the

denominator cannot be divided by the same number to arrive at a lower valued

numerator and denominator. For example: 3/4 is at its lowest terms because the

numerator 3 and the denominator 4 cannot be divided by the same number to lower

their values.

b. The fraction 4/8 is not at its lowest terms because the numerator 4 and the

denominator 8 can both be divided by the same number to lower their values. The

largest number that the numerator 4 and the denominator 8 can be divided by is 4.

44 = 1

84

2

Therefore, 1/2 is 4/8 at its lowest terms.

c. Reduce the following fractions to their lowest terms (if they can be reduced). If

they are at their lowest terms, indicate this by placing the same fraction on the answer

side of the equal sign:

(1)
