Suppose c = ab, where a, b, and c are integers and a and b are prime. How many positive integers less than or equal to c
are neither evenly divisible by a nor evenly divisible by b? (Use the subtraction rule from the text).

help please?

well..I am ready to help you to find answer on your own.....ok...I think you will b abletofigure out from what I right.... if not ask

anonymous · Answer

let us take an example... let 'a' =2 and 'b'=3
therefore the product will be $$'ab' = 2 \times  3 = 6$$
now how many times 2 can be evenly divisible by 3 = ?
and how many times 3 can be evenly divisible by 2 = ?
(if you relpy or try to provid answer to above questions I will write next steps...because...I don't like to write answer directly)
