A negative times a negative results to a positive number, but when two negative numbers are added to each other, it still results to a negative number.

Which number can you add to any rational number to obtain an irrational number?

Mars2501 [29]

I think any irrational number would do this? I'm not positive though. Some examples may be pi or the square root of 2.

How do you answer this question.

Ipatiy [6.2K]

Lets write this out:-

$\frac{50}{100} + \frac{30}{100}$

To answer this we just need to add the numerators of both fractions because the denominator's are already common multiples.

$\frac{50}{100}+ \frac{30}{100} = \frac{80}{100}$

Now lets simplify $\frac{80}{100}$ .

$\frac{80/20}{100/20}= \frac{4}{5}$

So, $\frac{50}{100}+ \frac{30}{100} = \frac{80}{100}= \frac{4}{5}$

Hope I helped ya!! xD
