Paul used 1 and 1/4 gallons of paint to cover 3/8 of the walls in his living room. how many gallons of paint will paul need to paint all the walls in his living room?

2 5/8

Step-by-step explanation:

1 1/4 times 2 = 2 4/8

then 1/4 divided by 2 = 1/8

next 2 4/8 + 1/8 = 2 5/8

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.
