Question

which is a rational number

sqrt7 3/10 TT sqrt8

Answer 1

A rational number is a number that can be expressed as the quotient of two integers (where the denominator is not zero).

Among the given options:

- \( \sqrt{7} \) is not a rational number because it cannot be expressed as a fraction of two integers.
- \( \frac{3}{10} \) is a rational number because it is the quotient of the integers 3 and 10.
- \( \sqrt{8} \) is not a rational number (though \( \sqrt{8} = 2\sqrt{2} \), which is also not a rational number).

Therefore, the rational number among the options you provided is \( \frac{3}{10} \).
