What is the ratio from m to n in 9n= 3m 3/1 1/3 1/6 6/1

3/1

Step-by-step explanation:

We want the ratio from m to n, or rewritten  m/n

9n = 3m

Divide each side by n

9n/n = 3m/n

9 = 3m/n

Now divide each side by 3

9/3 = 3m/3n

3 = m/n

We can divide the 3 by 1 and it is still the same number

3/1 = m/n

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.
