Answer:
All of the following proportion are equivalent except option Option C .
[tex]\frac{a}{d} = \frac{c}{b}[/tex]
Step-by-step explanation:
Proportion states that the two equivalent ratios or fractions are equal.
Let w , x , y and z are in proportion,
if the two quantities is equal to the ratio of two last quantities.
i.,e [tex]\frac{w}{x} = \frac{y}{z}[/tex] iff [tex]wz = xy[/tex]
Option A:
[tex]\frac{a}{b} = \frac{c}{d}[/tex]
By cross multiply we get;
[tex]ad = bc[/tex]
Option B :
[tex]\frac{b}{a} = \frac{d}{c}[/tex]
By cross multiply we get;
[tex]bc= ad[/tex]
Option C:
[tex]\frac{a}{d} = \frac{c}{b}[/tex]
By cross multiply we get;
[tex]ab = cd[/tex]
Option D:
[tex]\frac{a}{c} = \frac{b}{d}[/tex]
By cross multiply we get;
[tex]ad = bc[/tex]
Therefore, all of the following in the given options are proportion except option C
