If 65%=x/100 then x = ?

65

Why?

This can be rewritten as;

0.65 = x/100

It can be rewritten again to get x on the left side alone;

-x/100 = - 0.65

Now, multiply each term by - 100 to further distinguish x;

x = 0.65*100

Now, solve;

x = 65

There's your answer.

Check:

0.65 = 65/100

0.65 = 0.65
