Answer:

a) n > 3 Any number greater than 3 is an answer. So, 5 could be a solution.

b) n < 3 Any number less than 3 is an answer.
So, 2 could be a solution.

c) n =
(1)/(3) The only solution is
(1)/(3)

Explanation:

a:

3
(1)/(5) x
(3)/(n) < 3
(1)/(5)


(16)/(5) x
(3)/(n) <
(16)/(5) Converted to an improper fraction


(48)/(5n) <
(16)/(5)


(48)/(5n) x
(5)/(48) <
(16)/(5)x
(5)/(48) multiplied both sides by
(5)/(48) to isolate the variable


(1)/(n) <
(1)/(3)


(n)/(1) x
(1)/(n) <
(n)/(1) x
(1)/(3) Multiplied by sides by
(n)/(1) to isolate the variable

1 <
(n)/(3)

1 x 3 <
(3)/(1) x
(n)/(3)

3 < n

n > 3

b:


(16)/(5) x
(n)/(3) <
(16)/(5)


(5)/(16) x
(16)/(5) x
(n)/(3) <
(5)/(16) x
(16)/(5)


(n)/(3) < 1


(3)/(1) x
(n)/(3) < 3 x 1

n < 3

c:


(16)/(5) x
(3)/(n) =
(16)/(5)


(48)/(5n) =
(16)/(5)


(5)/(48) x
(48)/(5n) =
(5)/(48) x
(16)/(5)


(1)/(n) =
(1)/(3)


(n)/(1) x
(1)/(n) = 3n

1 = 3n


(1)/(3) =
(3n)/(3)


(1)/(3) = n

n =
(1)/(3)
