| 00:0-1 | When comparing these two fractions notice that they have different | |
| 00:03 | denominators eight and 12 fractions that have different denominators are | |
| 00:09 | called Unlike fractions to compare . Unlike fractions , we | |
| 00:13 | first write them as like fractions by finding a common | |
| 00:16 | denominator . The common denominator of eight and 12 is | |
| 00:20 | simply the least common multiple of eight and 12 , | |
| 00:23 | which is 24 . To get a 24 in the | |
| 00:27 | denominator of the first fraction , we multiply the numerator | |
| 00:30 | and denominator by three To get 15/24 To get 24 | |
| 00:38 | in the denominator of the second fraction . We multiply | |
| 00:41 | the numerator and denominator by two To get 14/24 . | |
| 00:48 | Now we're comparing like fractions because they have the same | |
| 00:51 | denominator and remember to compare like fractions , we simply | |
| 00:57 | compare the enumerators Since 15 is greater than 14 . | |
| 01:01 | We know that 15/24 is greater than 14/24 . This | |
| 01:07 | means that 5-8 Is greater than 7/12 . |
