The fraction 4 over 2100 can be simplified to 1 over 700.
92/1500 = 23/375
3/140
(700/1500) X 100 Cancel down bu '100' (7/15) X 100 Cancel down by '5' (7/3)X20 = 140 / 3 = 46.666.... % The Answer!!!!!
Yes: 1500/18000 = 1/12
700 is already simplified
It is: 23/250
15/19
1500-700 = 800
1500 + 700 = 2200
There are: 1500+700 = 2200 years
700 + 800 = 1500/2 = 750
