Question

This table shows the ratio of the number of adults to the number of students on a class field trip. A 2-column table has 4 rows. Column 1 is labeled Number of adults with entries 1, 2, 4, 6. Column 2 is labeled Number of students with entries 7, x, 28, y. Which values are missing from this table? x = y =

Answer 1

x = 14 and y = 42

Explanation:

From the two entries that have both the numbers od adults*A) and students(S) we find a ratio of S/A to be 7 for both cases. We'll make the assumption that is the same ratio in the two cases involving x and y.

To find x and y, multiply the number of adults by 7 to find the number of students,

x = 14 and y = 42

A S Ratio S/A = 7

1 7 7

2 x 14

4 28 28

6 y 42
