Question

I need help with pre algebra.

Answer 1

Irrational:
`√(2)` ≈ 1.4

Explanation:

And irrational number is when the answer cannot be written as a fraction. So, is the answer was one half, it would be rational because it's a fraction.
`((1)/(2))`

The square root of 2 is 1.414, and this cannot be written as a fraction. Therefore, it is irrational.
