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
Plane, think of planes as a rectangular shape. Rays and lines are just arrows. And a point is just one single dot
