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
Rationale: When subtracting, if fractions do not have the same denominator, change the fractions so they have the small-est common denominator. The greatest common denominator would not simplify the fractions for subtracting. Being equiv-alent 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.
