If a and b are positive integers, what is the value of a + b ?
(1) a/b = 5/8
(2) The greatest common divisor of a and b is 1.
i will go for c
st 1 just a ratio between a and b
insufficient to find a+b
st2 NO common factor between a and b
could be 7 AND 9 OR 5 AND 8
a+b= 5+8 = 13
Plz correct me if i am wrong thanks
