Both are rational numbers.

Step-by-step explanation:

A rational number is any number writted as a/b, with a and b being integers (b 0).

1) As 6.969= , and 6969 and 100 are integers, then 6.969 is a rational number.

2) As 3=, then 3 is a rational number.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
