I believe problem number 8 was , which is irrational.
I believe problem number 14 may be , which is rational, but if it was , then it is irrational
0.2222.... = is a rational number
0.303030....= is a rational number
Irrational numbers generate endless decimals that have no repeating pattern.
Repeating decimals are always rational. To express them as a fraction, you can set up an "equation" and solve it, like this:
= 0.2222...
= 2.2222...
= 2.2222... - 0.2222... =
So --> --> -->
= 0.303030...
= 30.303030...
= 30.303030... - 0.303030... =
So --> --> --> , which simplifies to
