Answer: There are 8 seats that were occupied.
Step-by-step explanation:
Since we have given that
Forty percent of the 20 seats were taken.
So, we have to write 40% as a reduced fraction,
So, it will be
[tex]\frac{40}{100}=\frac{4}{10}=\frac{2}{5}[/tex]
Now, we need to find the number of seats that were occupied ,
So, it will be
[tex]\frac{2}{5}\times 20\\\\=2\times 4\\\\=8[/tex]
Hence, there are 8 seats that were occupied.
