1. the product of an integer and 5 is greater than -32. find the least integer that makes this true.
5n > -32
 n > -32/5
 n > -6.4

Since n is an integer, the least one greater than -6.4 is -6
2. the quotient of an integer and -3 is less than -18. find the least integer that makes this true.
n/(-3) < -18
n > (-18)(-3)
n > 54

The least integer greater than 54 is 55
3. explain how the lcm of a set of numbers can be equal to the greatest number in the set.
Take the set of numbers {2,4}.  lcm(2,4) = 4, the greatest number in the set.
This is so often the case, I can't see why they would ask this.

            I will answer question (3), ONLY.


LCM of a finite set of positive integer numbers is equal to the greatest number in the set

      IF  and  ONLY  IF

the greatest number in the set is a MULTIPLE of all other numbers in the set.
