Do these ratios form a proportion?
28 elementary school students : 77 middle school students
46 elementary school students : 79 middle school students
To determine if these ratios form a proportion, we need to compare the fractions created by both ratios.
For the first ratio, the fraction is 28/77.
For the second ratio, the fraction is 46/79.
To determine if these fractions are equal, we can cross multiply and see if the resulting products are equal.
For the first ratio, cross multiply: 28 * 79 = 2212.
For the second ratio, cross multiply: 46 * 77 = 3542.
Since 2212 is not equal to 3542, the fractions are not equal. Therefore, these ratios do not form a proportion.
