$20 %$ $20%$ were not over the net.

Explanation:

If she served over the net 16 times, it means there were 4 times that she did not.

The fraction of misses is $\frac{4}{20}$ $4/20$

To find the fraction as a percent:

method 1 Make the denominator into 100.

$\frac{4}{20} \times \frac{5}{5} = \frac{20}{100} = 20 %$ $4/20 xx 5/5 = 20/100 = 20%$

method 2 Multiply the fraction by 100%

$\frac{4}{20} \times 100 % = 20 %$ $4/20 xx 100% =20%$

method 3 100% - % over the net

$\frac{16}{20} = 80 %$ $16/20 = 80%$ were over the net,

$100 % - 80 % = 20 %$ $100%-80% = 20%$ were not
