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}
