To simplify 60 over 360, you can divide both the numerator and the denominator by their greatest common divisor, which is 60. This gives you 1 over 6. Therefore, 60 over 360 simplified is 1/6.
170
It is: 50/60 = 5/6 simplified
-475 over 60 simplified = -95/12
heh, well if you do the math you will find out and to my calculations, no it can not be simplified
1/4 (simplified from 15/60)
It is: 60/100 = 3/5 simplified
It is: 2/60 = 1/30 simplified
It is: 63/60 = 21/20 simplified
6 over 20 EDIT - it will simplify even further to 3/10 !
17 over 60 cannot be simplified because 17 is a prime number and has no factors in common with 60.
No because: 60/105 = 4/7 simplified
