For a field trip, 56 students registered. On the day of the field trip, 7 students were unable to go. Which decimal describes the ratio of students who were unable to go to the number of students who registered for the field trip?

Answer 1

For a field trip, 56 students registered. Denote n=56.

On the day of the field trip, 7 students were unable to go. Denote m=7.

The ratio of students who were unable to go to the number of students who registered for the field trip is

$\dfrac{m}{n} =\dfrac{7}{56}=\dfrac{1}{8} =0.125.$

Answer: 0.125.

Answer 2

The ratio is 7/56 or 7:56, so the decimal that would be used to describe the ratio of students who were unable to go on the trip versus the number of students registered would be .125, or rounded to .13
