2.874192 Cups= 680 Milliliters
2 and 7/8 cups equals 681 ml.
The cup is a measurement of volume, and the gram is a measurement of weight. Therefore, in order to do this a certain substance would have to be weighed out at 658 grams, its dimensionality measured in a cubical manner, then converted to cups. Note: each substance has its own specific gravity (density), and so the solution to this problem would not be the same using sand as it would be using flour and so on.
680
24% of 680= 24% * 680= 0.24 * 680= 163.2
680
12% of 680= 12% * 680= 0.12 * 680= 81.6
2% of 680 = 2% * 680 = 0.02 * 680 = 13.6
15% off of 680 = 85% of 680 = 680*85/100 = 578
100 cubic centimeters = 100 milliliters. 1 cubic centimeter is the same as 1 milliliter in volume.
680+250 is 930. 680 + 250 930
680 X 1/8 = 680/8 = 85
It is then 680 because 5 rounds up to 10
