80% of what # = 12000

15,000

Step-by-step explanation:

Whenever I think about solving problems with percentages, I know that I either have to multiply or divide to get the answer.

In this, in other to get the bigger number, aka the denominator (which is essentially the number that is being solved for to obtain the %), I know I have to divide the smaller number by the percentage.

80% = .80

(Because it needs to be a decimal)

12,000 divided by .80 = 15,000

Hope this helps!

step-by-step explanation:

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.
