00:0-1 | The ratio of one number to another is the result | |
00:04 | of the first number divided by the second number . | |
00:09 | For example , in the diagram shown , if we're | |
00:13 | asked to find the ratio of the measure of angle | |
00:15 | A to the measure of angle be . We take | |
00:19 | the measure of angle A . Yeah , divided by | |
00:26 | the measure of angle be . And since the measure | |
00:30 | of angle a is 60° And the measure of Angle | |
00:34 | B is 80°, , we have 60/80 . Yeah . | |
00:44 | Notice that 60/80 can be reduced because 60 and 80 | |
00:49 | have a greatest common factor of 20 . So we | |
00:53 | divide both 60 and 80 by 20 . Yes . | |
01:00 | Mhm . To get three over four . So the | |
01:08 | ratio of the measure of angle a to the measure | |
01:11 | of Angle B is 3/4 . Remember to always reduce | |
01:17 | if possible when finding a ratio . It's important to | |
01:22 | understand that a ratio can be written in three different | |
01:26 | ways . For example , the ratio 3/4 can also | |
01:32 | be written as 3-4 Or 3:4 . Mhm . Make | |
01:45 | sure you're familiar with all three ways to write a | |
01:49 | ratio |
