I've thought about it before, and none of my teachers can ever answer.

It's a fraction. How could it be an irrational number? It makes sense. The square root of negative 2: now that's an irrational number.

When a rational number is expressed as a decimal, then either the decimal will terminate or there will be a predictable pattern of digits. But when an irrational number is expressed as a decimal, then, clearly, the decimal cannot terminate -- for if it did, the number would be rational so in retrospect, 1/7 is an irrational number because it cannot and does not terminate.
ie - 1/7 = 0.1428571 . . . and on and on and on.
However as you present it in fractional form, it is expressed and in fact is a rational number.
Where did your teachers go to school? Sounds like they need to go back.

1/7 is a rational number because it can be expressed as a faction even though the decimal version of it can go on forever.
An irrational number is a number that cannot be expressed as a fraction for any integers and . Irrational numbers have decimal expansions that neither terminate nor become periodic. Every transcendental number is irrational. - as quoted from mathworld.

No number that can be expressed as a fraction is irrational. A bit delusional, but not irrational.

no, it is a rational number since it repeats

no....its rational
a rational no. is in the form p/q where p and q are integers and q is not equal to zero
