Answer :

To decrease 225 by 68% you would multiply 225 by 0.68 and then subtract the result from 225. 225 x .68 = 153. Then 225 - 153 = 72. The final answer is 72.

We are decreasing so, we first of find 68% of 225

=  68 / 100  * 225  =  17/ 25 * 225        That is using 4 into 68 and 100

17/5  * 45                               Using 5 into 25 and 225.

17 * 9 =    153.

Since we are decreasing then we are going to subtract this result from 225.

If we were increasing we would have added.

=  225 - 153 = 72.

That's our answer.  Cheeers.
