Question 7

In the following question out of the four options only one is correct, write the correct answer.

If a and b are positive integers, then the solution of the equation ax=b has to be always:

(a) positive

(b) negative

(c) one

(d) zero

Answer 1

If ax=b, then $x=\frac{b}{a}$
Since, a and b are positive integers.
So, $\frac{b}{a}$ is also positive integer.
Hence, the solution of the given equation has to be always positive.
