When subtracting, if fractions do NOT have the same denominator, change the fractions so they have the:
A) greatest common denominator
B) smallest common denominator
C) equivalent of 1
D) number 100 as the denominator
B) smallest common denominator
When subtracting, if fractions do not have the same denominator, change the fractions so they have the smallest common denominator. The greatest common denominator would not simplify the fractions for subtracting. Being equivalent to 1 would mean that there would be no subtraction needed. A denominator of 100 (or a multiple of 10) is only used in calculating percentages.
