Is the range from 2 divided by 1 to positive infinity 0 to 2

Is the range from 2 divided by 1 to positive infinity 0 to 2

The algebraic formula is 2 / N, n > = 1. The hyperbola is decreasing in the first quadrant, so when n = 1, the maximum value is 2, and when n tends to be positive infinity, the minimum value is close to 0, so the value is (0,2]

If 0 can be divided by 1, can 1 be divided by 0?

No

Is the positive infinity obtained by dividing 1 by 0 or by dividing 1 by infinitesimal? Why
Such as the title
If 1 divided by 0 is not positive infinity, what does it equal

1 divided by 0 doesn't make sense

What's the original number of a simplest fraction, where the numerator plus one equals three eighths and the numerator minus one equals one third?

The numerator is x, the denominator is y, (1 + x) / y = 3 / 8, (x-1) / y = 1 / 3, x = 17, y = 48. The original number is 17 / 48
