To find out how many hours it rained, divide the total rise in the river by the amount it rose every hour.
First convert the mixed number into an improper fraction. We do this by multiplying the denominator to the whole number, adding it to the numerator, which becomes our new numerator, and we keep the denominator the same:
When dividing fractions we flip(the reciprocal) the one we're dividing by and multiply:
Multiply the numerators and denominators together:
Simplify by dividing:
So it rained for 10 hours.

Answer:
= Irrational
6 = Natural, Whole, Integer, Rational
= Rational
-2 = Integers, Rational
Explanation:
See attached photo! (it is hard to explain in words haha)
Side note: All natural numbers are rational numbers, but not all rational numbers are natural numbers (this applies differently to all sections, like all integers are whole, but not all whole are integers, etc)
Side note #2: Whole numbers are just natural numbers AND zero
Hope this is correct (or at least helps), have a nice day! :D
