Which numbers are "irrational" and which numbers are "rational"? 4/5 √(4) /5 √(25) /4 \pi

Question

Which numbers are "irrational" and which numbers are "rational"?

4/5

`√(4)` /5

`√(25)` /4

`\pi`

Answer 1

if something can be solved to a/b its rational

4/5 is rational already

√4/5 = 2/5 so its rational

√25/4 = 5/4 so its rational

π = is irrational because its 3.14159.....and on and on it can never be rationalized
