= percussionists.

1. of 800 cars that drove on a street during a week, 0.75% exceeded the 25 miles per hour speed limit by more than 10 miles per hour. how many cars drove over 35 miles per hour?

the number of cars driving over 35 miles per hour is
% of
=·800
= drivers

Explanation:

Step1: Solve problem 1

The number of percussionists is \(20\%\) of \(60\).
Convert \(20\%\) to decimal: \(20\%=\frac{20}{100} = 0.2\)
Then \(0.2\times60=12\)

Step2: Solve problem 2

The number of cars driving over \(35\) miles per hour is \(0.75\%\) of \(800\)
Convert \(0.75\%\) to decimal: \(0.75\%=\frac{0.75}{100}=0.0075\)
Then \(0.0075\times800 = 6\)

Answer:

1. The first box: \(20\), the second box: \(0.2\), the third box: \(12\)
2. The first box: \(0.75\), the second box: \(800\), the third box: \(0.0075\), the fourth box: \(6\)
