How do you find out what percentage a number is of a number?
question: find the percentage A is of B = (B-A)/B x 100 . You must then take the answer and subtract it from 100 to get the correct answer, which would make the formula: (B-A)/B x 100 = C, 100 - C = percentage A is of B for example, find what percentage 57 is of 90: B - A 90-57=33 /B 33/90=0.3666 x 100 0.3666 x 100 = 36.66. 100 - 36.66 = 63.33, which is the percentage that 57 is of 90
What is XC in Roman numerals?
In the Roman numeric system, symbols are given value. When a smaller value symbol proceeds a higher value symbol, then the smaller value symbol is subtracted from the high value symbol. In this case XC is equal to 90 (X =10, C = 100. So XC equals 100 - 10 or 90). The symbols that hold numeric are I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1,000.
