<h3>The ratio in three ways are 500 : 125 or 100 : 25 or 4 : 1</h3>
<em><u>Solution:</u></em>
Given that,
Five hundred sixth-grade students were surveyed
Which means,
sixth-grade students = 500
125 had traveled on an airplane
<em><u>What is the ratio of total sixth-grade students to the number of students who had traveled on an airplane?</u></em>
Therefore,
total sixth-grade students : students traveled on airplane = 500 : 125
<h3>Ratio = 500 : 125</h3>
Reduce to lowest terms,
Divide both sides by 5
<h3>Ratio = 100 : 25</h3>
Further reduce to simplest terms,
Divide both sides by 25
<h3>Ratio = 4 : 1</h3>
Thus the ratio in three ways are 500 : 125 or 100 : 25 or 4 : 1
