If i'm not wrong,i think the answer is:

30％=0.3
X=0.3+12=12.3

Since we're trying to find X, what is X? X is the whole. I'm using the "Part = Percent x Whole" formula (Whole = Part ÷ Percent) to find the answer. 12 ÷ 0.3 (30% in decimal form) = 40. And we can do the opposite to see if it's right, 40 x 0.3 = 12.

Hope this helps,

X and y are positive integers. explain why incorrect to claim that

dedylja [7]

You can find counterexamples to disprove this claim. We have positive integers that are perfect square numbers; when we take the square root of those numbers, we get an integer.

For example, the square root of 1 is 1, which is an integer. So if y = 1, then the denominator becomes an integer and thus we get a quotient of two integers (since x is also defined to be an integer), the definition of a rational number.

Example: x = 2, y = 1 ends up with $\frac{2}{\sqrt{1}} = \frac{2}{1}$ which is rational. This goes against the claim that $x/\sqrt{y}$ is always irrational for positive integers x and y.
