N - p% = N - p% of N = N*(1 - p%) = N*(1 - p/100) or N*(100 - p)/100
128 = N - 0.20N; 128 = .80N; N = 160
If 15 percent of a number N is 0.3 what is 45 percent of N
To calculate 25 percent of a number ( N ), you can multiply ( N ) by 0.25 (since 25 percent is equivalent to 0.25 in decimal form). Alternatively, you could divide ( N ) by 4, as 25 percent is one-fourth of the whole. Both methods will give you the same result.

Divide ' 100 X ' by ' N '. The answer is the number.
20% of n = .2 * n, where n is a number.
let the number be n, then 37% of n is .37n and add that to the number and you have n+.37n or n(1.37)
Designate the unknown base number as n. Then 0.25 n = 850 or n = 3400. 1 percent of this is 34.
you multiply the number by 1.06 let N = number 0.06N + N = 1.06N
long nfact (long n) { long result; if (n < 2) return 1; for (result = n; n > 1; --n, result *= n); /* only works up to n==12 */ return result; }
0.6*N 0.6*N 0.6*N 0.6*N
