two times of a number is 100% increase in the number if we take half the number what would be the decrease in percent

Answer:50%

Step-by-step explanation:

Let us assume the number is N.

When you multiply it by 2, you get:

2 x N = 2N

And that is increasing N by 100%

N + N = 2N

Also, taking half of N would be:

½ x N = N/2

Half of N is 50% of N.
