| 00:0-1 | To find the increase or decrease . When a number | |
| 00:03 | changes from 110 to 441st determine whether the number is | |
| 00:09 | increasing or decreasing . Since the number changes from 110 | |
| 00:14 | to 440 it's going up so it's increasing now to | |
| 00:19 | find the percent increase . We divide the amount of | |
| 00:23 | change both . Yeah . Yeah . Bye . The | |
| 00:32 | original number . Yeah . The amount of change is | |
| 00:42 | the difference between the two numbers which in this case | |
| 00:45 | is 440 -110 . Yeah . And the original number | |
| 00:55 | is 110 . Notice that when finding the amount of | |
| 00:59 | change we always take the larger number minus the smaller | |
| 01:03 | number so that the amount of change ends up positive | |
| 01:07 | . So 440 -110 is 330 And we have 330 | |
| 01:14 | over 110 . 330 divided by 110 is three . | |
| 01:20 | But remember that we want to write our answer as | |
| 01:23 | a 1% . So we move the decimal .2 places | |
| 01:26 | to the right and fill in the missing positions with | |
| 01:29 | Zeros . So when a number changes from 110 to | |
| 01:33 | 440 , it increases by 300 percent . |
