n X .15 = 9 9 / .15 = n 9 / .15 = 60
15 - n when n equals 9 = 6
9
n = 6050 = 100 Using the criss cross multiplication trick we get 50X60=3000 and 100 X n=100n 3000 = 100n 100 = 100 So 3000÷100=30 and 100n÷100=n. n=30 or 60% of 50 is 30
90 is the 100%.100% :N = 30% : 2730%N = 27 (100%)N = 27(100%)/30%N = 2700/30N = 90
n X .15 = 9 9 / .15 = n 9 / .15 = 60
15 - n when n equals 9 = 6
n is 6

N=19.
N - 425 = 9 n - 425 + 425 = 9 + 425 n = 434
1.5 * 90 = n 135 = n
Substituting n for 30 gives 6 x 9 x 30 = 1620.
N=9
n + 9 = 4747 - 9 = nTherefore n = 38.
