D. 40
Answer:B
In the equation above, if a and b are positive integers and is in its simplest reduced form, what is the value of a ?
A. 2 B. 9 C. 18 D. 40
Explanation: B The lowest number that both 8 and 10 are factors of is 40. Convert the fractions to a denominator of 40: + = . There is no factor that 9 and 40 have in common, so the fraction cannot be reduced. The number in place of a in is 9, so the answer is (B). Be careful! The value of b is in (D).
