In general, a "C" grade tends to be equivalent to a percentage somewhere in the 70s. There is not one set standard, so it varies among schools. Each institution determines its own grading policies.
Know MoreFor example, at the University of Washington in Seattle, a "C" runs from 75 percent to 79 percent. An 80 is considered a "C" to "C+." At the other end of the scale, 73 or 74 percent is a "C-," while a 72 is a "C" to "D+." Other schools have slightly lower percentages for a "C." At the University of Northern Iowa in Cedar Falls, a "C" is 73 to 76 percent. A "C-" covers 70 to 72, while anything in the high 70s equals a "C+."

Full Answer >Thirty percent of 40 equals 12. This can be calculated by multiplying 30/100 x 40. It can also be found by multiplying 0.3 and 40. In both instances, the answer is 12.
Full Answer >Thirty percent of $60 is $18. The mathematical equation used to solve this problem is: 0.30 x $60 = N. An alternative method is to multiply 30 by $60 and then divide the answer by 100. Thus, 30 x $60 = $1,800, and $1,800 / 100 = $18.
Full Answer >Percent elongation quantifies the ability of an element or compound to stretch up to its breaking point. It is measured by dividing the change in length (up to the breaking point) by the original length, then multiplying by 100. Materials with a higher percentage elongation can stretch more before breaking.
