I am running into problem with statement 1 + statement 2 scenario:
OA is C
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
A>0, B>0 and both are integers
a + b= ?
1. this is just a ratio, won't get us a + b
the best it does for us is to rephrase the question in terms of either variable
insuff
2. thus, a and b have no common prime factors. but we know nothing abt value of a and b
1. + 2.
if a and b have no prime factors in common, CAN they can STILL have other factors in common?
I guess the answer to that is NO
because all numbers are composed of prime factors
and a and b don't have any prime factors in common, then that implies they have nothing in common
thus, a = 5 and b = 8
suff
Please correct my thinking...thanks
