Final answer:
To find the number of cars that are not silver in the car park, subtract the number of silver cars from the total number of cars.
Step-by-step explanation:
To find the number of cars that are not silver in the car park, we need to subtract the number of silver cars from the total number of cars.
Given that 4/7 of the cars are silver, we can calculate the number of silver cars by multiplying 4/7 by the total number of cars (700).
So, the number of silver cars is (4/7) * 700 = 400.
To find the number of cars that are not silver, we subtract the number of silver cars from the total number of cars: 700 - 400 = 300.
Therefore, there are 300 cars in the car park that are not silver.
