Question

In Volleyball , players serve the ball to the opposing team . If the opposing team fails to hit the ball , the services is called an ace . A player's ace average is the number of aces served divided by the number of games played . A certain player has an ace average of 0.3 and has played in 70 games this season .
How many aces has the player served ?

Answer 1

To solve, I would write an equation like this: 0.3=x/70 , where x is the number of aces divided by 70 games and 0.3 is his ace average.

0.3=x/70
x=70x0.3
  =21

The player has served 21 aces.

Check:
21/70
=0.3
