When carla looked out at the school parking lot she notice that for every 2 minivans there were5 other types of vehicles if there are 161 in the parking lot how many of them are not minivans

The ratio of minivans to other vehicles is 2:5.
Since there's 161 total vehicles, the ratio actually has a constant, k.
In reality, the unsimplified ratio is 2k:5k
In ratios, you'll get the total if you add both the numerator and denominator.
So:
2k + 5k = 161
7k = 161
k = 23
5 * 23 = 115
115 vehicles are not minivans.
Good luck!
