here is a list of 2 each fractions I had to turn them into 2 w\ common denomators...
1.3\4 and 3\8=6\8and 3\8
2.2\3 an 1\9=6\9an 1\9
3.3\5an 1\3=18\24an4\24
5.1\4an9\14=7\28an18\28
6.7\12an1\10=35\60an6\60
7.2\5an2\3=6\15an10\15
8.4\11an1\2=8\22an11\22
9.3\10an11\15=45\150an110\150
9 is actually 9\30 and 22\30
All are right except for 3 and 9.
3. is 9\15 and 5\15 sorry I read my paper wrong! oohps
Right! :-)
To find a common denominator for fractions, you need to find the least common multiple (LCM) of the denominators. Here are the steps for finding the common denominators for each pair of fractions you provided:
1. For 3/4 and 3/8:
- The denominators are 4 and 8, respectively.
- The LCM of 4 and 8 is 8.
- Multiply the numerators and denominators by the appropriate factors to get a common denominator:
- (3/4) * (2/2) = 6/8
- (3/8) * (1/1) = 3/8
2. For 2/3 and 1/9:
- The denominators are 3 and 9, respectively.
- The LCM of 3 and 9 is 9.
- Multiply the numerators and denominators by the appropriate factors to get a common denominator:
- (2/3) * (3/3) = 6/9
- (1/9) * (1/1) = 1/9
3. For 3/5 and 1/3:
- The denominators are 5 and 3, respectively.
- The LCM of 5 and 3 is 15.
- Multiply the numerators and denominators by the appropriate factors to get a common denominator:
- (3/5) * (3/3) = 9/15
- (1/3) * (5/5) = 5/15
4. For 1/4 and 9/14:
- The denominators are 4 and 14, respectively.
- The LCM of 4 and 14 is 28.
- Multiply the numerators and denominators by the appropriate factors to get a common denominator:
- (1/4) * (7/7) = 7/28
- (9/14) * (2/2) = 18/28
5. For 7/12 and 1/10:
- The denominators are 12 and 10, respectively.
- The LCM of 12 and 10 is 60.
- Multiply the numerators and denominators by the appropriate factors to get a common denominator:
- (7/12) * (5/5) = 35/60
- (1/10) * (6/6) = 6/60
6. For 2/5 and 2/3:
- The denominators are 5 and 3, respectively.
- The LCM of 5 and 3 is 15.
- Multiply the numerators and denominators by the appropriate factors to get a common denominator:
- (2/5) * (3/3) = 6/15
- (2/3) * (5/5) = 10/15
7. For 4/11 and 1/2:
- The denominators are 11 and 2, respectively.
- The LCM of 11 and 2 is 22.
- Multiply the numerators and denominators by the appropriate factors to get a common denominator:
- (4/11) * (2/2) = 8/22
- (1/2) * (11/11) = 11/22
8. For 3/10 and 11/15:
- The denominators are 10 and 15, respectively.
- The LCM of 10 and 15 is 30.
- Multiply the numerators and denominators by the appropriate factors to get a common denominator:
- (3/10) * (3/3) = 9/30
- (11/15) * (2/2) = 22/30
I hope this explanation helps! Let me know if you have any further questions.
