Prove that if a and b are integers such that b ≠ 0 and a | b , then | a | ≤ | b | .

To determine

To prove: If a and b are integers, such that b0 and a|b, then |a||b|.

Explanation

Given information:

a and b are integers such that b0 and a|b.

Formula used:

Divisor:

Let a,b be any integers, a is divisor of b, write as a|b if there is an integer c such that b=ac.

Proof:

Let a and b are integers such that b0 and a|b.

Then, there exists an integer x such that, b=ax
