To find:

The statement for the given equation.

Solution:

For "more" or "plus" we use "+" sign.

For "of" we use "×" sign.

Let x be the unknown number.

Two-fifths of nine is a number.

`(2)/(5)(9)=x`

Two-fifths of a number is nine.

`(2)/(5)x=9`

A number plus nine is the same as two-fifths of nine.

`x+9=(2)/(5)(9)`

These equation are different from the given equation. So, the options A, B and D are incorrect.

Nine more than two-fifths of a number is nine.

`(2)/(5)x+9=9`

It is same as the given equation. Therefore, the correct option is C.
