6/30 = 1/5 = 0.2
12/30 = 2/5
6 and 121 over 576
6/9 would be simplfied to 2/3
3/12 ÷ 7/10 = 30/84 simplfied to 5/14.
21/30 can be simplfied to 7/10
6/7 ÷ 9/10 = 60/63 simplfied as 20/21.

Yes it could be simplified.
It cannot be simplfied any further.
four over five (four-fifths) cannot be simplified
