Question

Five hundred sixth-grade students

were surveyed. Of these students
that were surveyed...
• 375 had been to a baseball game
• 270 own either a cat or a dog
• 125 had traveled on an airplane
3) What is the ratio of total sixth-grade students to the number of students who either want a cat or a dog? (Write the ratio in THREE ways)

Answer 1

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
