4/5*30 = (4/5)*30 = 0.8*30 = 24
4/5 + 1/6 = 24/30 + 5/30 = 29/30
4/5 = 24/30 4/6 = 20/30 4/5 is greater.
5/30 + 4/6 = 1/6 + 4/6 = 5/6
4/6-2/5=4/15. 4/6-2/5=20/30-12/30=8/30=4/15
3 and 5/6 + 1 and 4/5 = 23/6 + 9/5 = 115/30 + 54/30 = 169/30
yes 6 goes into both 30/24 = 5/4
24/30 = 4/5
5/6 minus 4/15 = 17/30
1/6 * 4/5 = 4/30 = 2/15
4 over 5
