the ratio of golf balls to tennis balls in the pro shop is 5 : 4. if there are 385 golf balls, how many tennis balls are there?

3 answers

Let x be the number of tennis balls in the pro shop.

According to the ratio, the number of golf balls is 5 times the number of tennis balls. So, we can write the equation:

5x = 385

Solving for x:

x = 385 / 5
x = 77

Therefore, there are 77 tennis balls in the pro shop.
77 is not the correct answer.
My apologies for the mistake. Let's solve it correctly:

Given that the ratio of golf balls to tennis balls is 5 : 4, and there are 385 golf balls.

Let the number of tennis balls be x.

According to the ratio, the number of golf balls is 5 times the number of tennis balls. So, we can write it as:

5/4 = 385/x

Cross multiply:

5x = 1540

x = 1540 / 5
x = 308

Therefore, there are 308 tennis balls in the pro shop.
