Question

Out of 32 students in a class, 5 said they ride their bikes to school. Based on these results. How many of 800 students in the school ride their bikes to school?

Answer 1

We can set a proportion.

 

5 / 32 = x / 800

 

 

where x is the number of students out of 100 who ride their bikes.

 

Cross multiply.

 

32x = 4000

 

 

Divide both sides of the equation by 32.

 

x = 125

 

 

125 students out of 800 students ride their bikes to school.
