There are 10 tennis balls, 2 soccer balls, and 8 basketballs. What fraction in simplest form are tennis balls?

10/20 = 1/2

6 tennis balls and 9 soccer balls. What fraction of the balls are tennis balls? *

To find the fraction of tennis balls, we need to determine the number of tennis balls out of the total number of balls. The total number of balls is the sum of tennis balls, soccer balls, and basketballs, which is 10 + 2 + 8 = 20.

So, the fraction of tennis balls can be calculated as:
Number of tennis balls / Total number of balls = 10 / 20.

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 10 and 20 is 10. So, dividing both by 10 gives:

10 / 20 = 1 / 2.

Therefore, the fraction of tennis balls, in simplest form, is 1/2.
