Let x represent the unknown nimber. Set up the equation and solve (15% is the same as .15)
.15 * x = 18 (next divide both sides by .15 to solve for x)
x = 120

18% of 15.00= 18% * 15= 0.18 * 15= 2.70
Let "x" be the number you're trying to find. (15/100) * x = 18 Now, solve for "x": (15/100) * x = 18 To isolate "x," you can multiply both sides of the equation by (100/15): x = 18 * (100/15) x = 1800/15 x = 120 So, the number is 120.
To find 18 percent of a number, multiply the number by 0.18. In this instance, 0.18 x 40 = 7.2. Therefore, 18 percent of 40 is equal to 7.2.
Finding 120 percent of a number is the same as multiplying the number by 1.2. In this instance, 1.2 x 18 = 21.6.
15% of 120 is 18.0.15 x = 18x = 18/ 0.15x = 120
