Answer :

fourth = 0.25
then
500*0.25=125
125*3=375
Answer: filled 375 seats.

Here is the correct answer. Please don't copy and paste.

The first step is to convert three fourths into a decimal.

In order to do so, I need to divide the numerator and the denominator.

3 ÷ 4 = 0.75

Now we need to multiply 0.75 by 500 beacause 0.75 were the number of seats filled and 500 was the number of seats.

0.75 x 500 = 375

So 375 seats are filled.

Hope this Helps!
