Is the number –5+7 rational or irrational?

1 answer

The expression \(-5 + 7\) can be simplified as follows:

\[ -5 + 7 = 2 \]

The number 2 is a whole number and can also be expressed as a fraction (such as \(\frac{2}{1}\)). Since both whole numbers and fractions where the denominator is not zero are considered rational numbers, the result, which is 2, is a rational number.

Therefore, \(-5 + 7\) is rational.
