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