Answer:
All of the following proportion are equivalent except option Option C .
\(\frac{a}{d} = \frac{c}{b}\)
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 \(\frac{w}{x} = \frac{y}{z}\) iff \(wz = xy\)
Option A:
\(\frac{a}{b} = \frac{c}{d}\)
By cross multiply we get;
\(ad = bc\)
Option B :
\(\frac{b}{a} = \frac{d}{c}\)
By cross multiply we get;
\(bc= ad\)
Option C:
\(\frac{a}{d} = \frac{c}{b}\)
By cross multiply we get;
\(ab = cd\)
Option D:
\(\frac{a}{c} = \frac{b}{d}\)
By cross multiply we get;
\(ad = bc\)
Therefore, all of the following in the given options are proportion except option C
