Basically ur just looking for the LCM (lowest common multiple) of all of these numbers.
3,7,12,14....lowest number that all 4 of these numbers go into evenly is 84.
so they will ring together next in 84 minutes (1 hr 24 minutes) making it 5:24 a.m.
(this is for fractions!!!!!!!!!!!!) 28/5 or 5 3/5
i think u just make it into 5.6/1 multiply by 10 which gets 56/10 and wala
but it's not simplified. 56 and 10 is divisible by 2 so u get 28/5 which is actually 5 3/5 (which is 5.6!!)
Okayuyyyyyyyyyyyyyyyyyyyyyyyyy
