Keep dividing top and bottom by any factor common to both. Here, 4 is an obvious factor. Some people would say 12 is even more obvious. Keep on doing it until you can no longer find any common factor.
It is: 48/120 = 2/5 simplified
120/48 = 30/12 = 5/2
2/5...48/24 is 2...120/24 is 5
81/120 = 27/40
2 over 5
Yes, as 57/120 can be reduced to 19/40.
4/9
2/5
10/11
To reduce 36/48, find the common factors of the numbers (12), and divide them out. 36/48 = 3/4
The answer is 2 over 5.
No it equals 40%
