If we try to simplify the ratio or try to multiply both by any number, we will get the equivalent ratio
Like :
[tex] \frac{4}{6} \\[/tex]
Divide ( simplify ) by 2
[tex] \frac{ \frac{4}{2} }{ \frac{6}{2} } \\ \\ \\ = > \frac{2}{3} [/tex]
Or multiply by any number,
[tex] \frac{4}{6} \\ \\ \\ = > \frac{4 \times 2}{6 \times 2} \\ \\ \\ = > \frac{8}{12} [/tex]
From the example, 2 / 3 and 8 / 12 are equivalent ratios to 4 / 6
