2: 3 and 12: 18 form a proportion
Step-by-step explanation:
When the two ratios are equal then they are said to be in proportion.
[tex]$\frac{2}{3}[/tex] ≠ [tex]$\frac{4}{12} = \frac{1}{3}[/tex]
So 2:3 and 4:12 are not in proportion.
[tex]$\frac{2}{3}[/tex] ≠ [tex]$\frac{6}{12} = \frac{1}{2}[/tex]
So 2:3 and 6:12 are not in proportion
[tex]$\frac{2}{3}[/tex] ≠ [tex]$\frac{12}{18} = \frac{2}{3}[/tex]
So 2:3 and 12:18 are in proportion
[tex]$\frac{2}{3}[/tex] ≠ [tex]$\frac{12}{36} = \frac{1}{3}[/tex]
So 2:3 and 12: 36 are not in proportion
