If I spent 2/5 of my money and I had #51.00 left,how much was my money?

To find out how much money you had initially, we need to divide the amount you have left by the fraction representing the portion you spent.

Let's call the amount of money you initially had "x."

You spent 2/5 of your money, so you have 3/5 of your money left, which is equivalent to #51.00:

3/5 * x = #51.00

To isolate x, we can multiply both sides of the equation by the reciprocal of 3/5, which is 5/3:

(3/5 * x) * (5/3) = #51.00 * (5/3)

On the left side, the 5s and 3s will cancel out, leaving us with:

x = #51.00 * (5/3)

Now, we can calculate the value of x:

x = #85.00

Therefore, you initially had #85.00.
