Answer 1

To determine the number of red cars in Bahrain Polytechnic car parking with a car ratio of 5 black to 3 red, solve the ratio equation 8x=344 to find x = 43. Multiply this by 3 to get 129 red cars.

Step-by-step explanation:

To find out how many red cars are in the Bahrain Polytechnic car parking when the ratio of black cars to red cars is 5:3 and there are a total of 344 black and red cars, we can set up the following equation based on the ratio:

• Let the number of black cars be 5x.
• Let the number of red cars be 3x.

According to the given ratio, 5x + 3x = 344. This simplifies to 8x = 344, so x = 344 / 8, which gives us x = 43.

To find the number of red cars, multiply the value of x by the number corresponding to red cars in the ratio: 3x = 3 × 43 = 129.

Therefore, there are 129 red cars in the parking lot.
