(ii) When a number is a multiple of 9 , it is necessarily a multiple of $3 .$
(iii) You get a job implies that your credentials are good.
(iv) Atmospheric humidity increase only if it rains
(v) If a number is not a multiple of 3 , then it is not a multiple of 6 .
Solution:
(i) If each of the angles of a rhombus measures 90°, then the rhombus is a square.
(ii) If a number is a multiple of 9, then the number is multiple of $3 .$
(iii) If you get a job, then your credentials are good.
(iv) If it rains, then the atmospheric humidity increases.
(v) If a number is a multiple of 6, then it is a multiple of $3 .$
