There are 37 students in a class. students go to science lab in groups that contain no more than 7 students. make a model to show the fewest number of science lab groups that will need to be formed with these 37 students.

step-by-step explanation:

sry but any answer choices

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
