Answer:
[tex]\frac{3}{4}[/tex] = [tex]\frac{9}{12}[/tex]
Step-by-step explanation:
The values are in proportion if the right side is a multiple of the left side
Consider
[tex]\frac{3}{4}[/tex] × [tex]\frac{3}{3}[/tex]
= [tex]\frac{3(3)}{4(3)}[/tex]
= [tex]\frac{9}{12}[/tex]
Thus [tex]\frac{3}{4}[/tex] and [tex]\frac{9}{12}[/tex] are in proportion
This does not happen for any of the other three.
