Which of the following tables represent this ratio? (High School)

Answer:
Table A
Explanation:
The ratio of x to y is 3 to 8.
To determine which table represents the ratio, convert the first pair of points in each of the options to their simplest form.
Option A
When x=15, y=40
[tex]\frac{x}{y}=\frac{15}{40}=\frac{3\times5}{8\times5}=\frac{3}{8}[/tex]Option B
When x=8, y=32
[tex]\frac{x}{y}=\frac{8}{32}=\frac{8}{4\times8}=\frac{1}{4}[/tex]Option C
When x=9, y=24
[tex]\frac{x}{y}=\frac{9}{24}=\frac{3\times3}{3\times8}=\frac{3}{8}[/tex]However, when x=15, and y=35
[tex]\frac{x}{y}=\frac{15}{35}=\frac{3\times5}{7\times5}=\frac{3}{7}[/tex]Therefore, the ratio in Option C is not constant.
Option D
When x=16, y=6
[tex]\frac{x}{y}=\frac{16}{6}=\frac{2\times8}{2\times3}=\frac{8}{3}[/tex]Therefore, the table that represents the given ratio is Option A.
Note:
• After using the first column in Table C, we find 3/8. But we already had 3/8 in Table A.
,• Since there is to be just one answer, we tested using another column in Table C.
,• If you test using another column in Table A, you will still get 3/8.
