Oh honey, of course it can be simplified. Just divide the top and bottom by their greatest common factor, which is 6 in this case. So, 210 divided by 6 is 35, and 36 divided by 6 is 6. Voila! 210 over 36 simplified is 35 over 6.
168/210 = 4/5
70
It is 2 over 3.
It is: 36/42 = 6/7 simplified
100 over 36 simplified = 25/9
80 over 36 simplified: 20 over 9 and as a mixed number it's 2 2/9
Yes, it can.
14/36
It simplified to 5/9.
It is: 3/5
4 over 144 simplified = 1 over 36
No.
