12/30 = 2/5
four over five (four-fifths) cannot be simplified
6/30 = 1/5 = 0.2
5 over 47 cannot be simplified any further, as it is already in its simplest form.
3/4 ÷ 12/5 = 15/48 which can be simplfied to 5/16.
Yes. 10 and 105 have a common factor of 5 .
2/5 ÷ 7/10 = 20/35 which is simplfied as 4/7.
8/17 ÷ 4/5 = 40/68 which can be simplfied to 10/17.
45/36 = 15/12 = 5/4
3/12 ÷ 7/10 = 30/84 simplfied to 5/14.
6 and 121 over 576
4/9
