To determine how many serves landed in, we can use the ratio provided: for every 2 serves that land in, 4 serves land out. This gives us a total of 6 serves (2 in + 4 out).
We can set up a proportion based on this ratio.
Let \( x \) be the number of serves that landed in. Then the number of serves that landed out would be \( 2x \) (because for every 2 serves that land in, there are 4 that land out).
According to the problem:
\[ x + 2x = 24 \]
Solving this equation:
\[ 3x = 24 \] \[ x = \frac{24}{3} = 8 \]
So, 8 serves landed in.
To find how many serves landed out:
\[ 2x = 2 \times 8 = 16 \]
Thus, if he hit 24 serves total, then 8 serves landed in and 16 serves landed out.
