Yes: 1/7
105/98 reduces to 15/14. 105/7 = 15 and 98/7 = 14
2/105 cannot be reduced.
6
No.
50/105 = 10/21
105/15 = 7
15/105 = 1/7
Yes. Divide 12 and 105 by 3. You then get 4 over 35 or 4/35.
3 and 2 over 7 = ( 3*7 + 2 )/ 7 = 23/7 7 and 1 over 15 = ( 7*15 + 1 ) / 15 = 106/15 The least common multiple of 7 and 15 is 105 So, 23/7 + 106/15 = 23*15 / 105 + 106*7 / 105 = 345 / 105 + 742 / 105 = 1087 / 105 = (1050 + 37 ) / 105 = 10 and 37 over 105
Yes, to 16/35
Yes, 2/35.
105/90 = 7/6 or 11/6
