Answer:
Unknown number = 36
Step-by-step explanation:
Equivalent ratio means,
[tex]\frac{x_1}{y_1}=\frac{x_2}{y_2}[/tex]
If [tex]x_1=2, y_1=9[/tex] and [tex]x_2=8[/tex],
[tex]\frac{2}{9}=\frac{8}{y_2}[/tex]
By cross multiplication,
2 × y₂ = 8 × 9
2y₂ = 72
[tex]\frac{2y_2}{2}=\frac{72}{2}[/tex]
y₂ = 36
Therefore, missing number in the denominator of the fraction will be 36.
