A) a must be a divisor of 60 if a is a factor of b and b divides 60
B) if b is a divisor of 60, then 60 is a multple of b
D) the largest that b and c can be are 20 and 30, respectively.....a is smaller than both....so...a cannot be 20
Sorry....I thought they wanted the true ones
C, E would be correct for the false ones !!!!
