Anna said that the product of 7/8 times 1 1/2 = 7/2 how can you tell that her answer is wrong? a: the denominator cannot be the same as one of the factors. b: the answer cannot be an improper fraction c: the answer must be less than 7/8. d: 78 of a number cannot be greater than the number.

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
