Verified Answer :

D is the only one not true

Answer:

\(\frac{2}{d} = \frac{5}{c}\)

Option d is correct

Step-by-step explanation:

Given that:

\(2d = 5c\)

Option d.

\(\frac{2}{5} = \frac{c}{d}\)

By cross multiply we have;

\(2d = 5c\)  which is true.

Option b.

\(\frac{5}{2} = \frac{d}{c}\)

By cross multiply we have;

\(5c =2d\)  which is true.

Option c.

\(\frac{2}{c} = \frac{5}{d}\)

By cross multiply we have;

\(5d =5c\)  which is true.

Option d.

\(\frac{2}{d} = \frac{5}{c}\)

By cross multiply we have;

2c = 5d

which is not true.

Therefore, all of the following are true except \(\frac{2}{d} = \frac{5}{c}\)
