00:00:00.000 --> 00:00:04.772
Here is the problem: Find the percentage change from 45 to 54.

2
00:00:05.222 --> 00:00:08.984
Measure how much a value changed relative to its original value.

3
00:00:09.784 --> 00:00:12.710
Subtract the original value from the new value.

4
00:00:13.160 --> 00:00:16.655
Divide the change by the absolute value of the original.

5
00:00:17.105 --> 00:00:18.719
Multiply by 100.

6
00:00:19.519 --> 00:00:22.224
So the answer is 20 percent (increase).

7
00:00:22.674 --> 00:00:24.973
The value increased by 20 percent.

8
00:00:25.773 --> 00:00:30.707
Check: 45 plus 20 percent of |45| equals 54.
