There are 516 cars in a parking lot. One-third are blue, one-half are red, and the rest are black. How many black cars are on the lot? Let's be accurate as possible.
User
Blue = 516 * (1 / 3) = 172 cars. Red = 516 * (1 / 2) = 258. Black = 516 - (172 + 258) = 86. There are 86 black cars on the lot.
The answer: 86.
