Zachary brought 7 dozen rolls of toilet paper for the office. the rolls were divided equally into 4 boxes. how many rolls are in each box?

Take 7 x 12 since 12 is a dozen. So 7 x 12 is 84.
Then 84 divided by 4 equals 21. So there would be 21 rolls in each box.

Rounding decimals is very similar to rounding other numbers. if the hundredths and thousandths places of a decimal is forty-nine or less, they are dropped and the tenths place does not change. for example, rounding 0.843 to the nearest tenth would give 0.8. , your welcome !
