You would need to divide.
You just continue to do the division, until you calculate the third digit after the decimal point. Then you round.
you would find the area of the bricks... 4x8=32... then divide 550 by 32 which equals 17.1875... the answer would be 18 because you would need that .1 of a brick so you could not round down
You would need to divide by -1/2.
The box will have a square foot coverage on the box. Multiply 198x185=36,630 square inches There are 144 inches in a square foot. Divide 36,630 by 144=254.375 Divide 254.375 by the number on the box. If you have ANY remainder then round UP. You can't round down. Also, many contractors add 10 percent to help with measurement.

The correct answer is .1 repeating because if you take a # like 4.86 square yards and find the feet for it you would have to divide by one ninth. If you need to cover a carpet with only that measurements and the area you need to cover is 110 feet squared you would multiply 110 by 4.86 then divide by 9 (feet in square yard) you would get 59.4 Then to prove it is .1 repeating multiply .1111 by 4.86 then multiply again by 110 you would get 59.39046. Round it and you get 59.4 there for the correct answer is .1 repeating.
To format the sections with different numbers of columns.
To find the grade percentage, you need to divide the number correct by the total number of questions. In this case, that would mean 510 divided by 562, which would equal .907 Move the decimal to the right 2 places (90.7%) and then round up if the number past the decimal is greater than 5...in this case, it is '7', so we would round up. The grade percentage would be 91%.
You would need to round it to the nearest whole number.
