12.25 hours is 12 hours and 15 minutes.
1225 pound = 87.5 stone
That is 13 and 1/2 hours
I would use a factor tree. 1225 245,5 49,5,5 7,7,5,5 5 x 5 x 7 x 7 = 1225
sqrt(1225) =
1225 245 [5] 49 [5] [7] [7] so the answer is 7x7x5x5 = 1225 1225 245,5 49,5,5 7,7,5,5
35 35X35=1225
It is: 1225 = MCCXXV
245x5= 1225
It is: 1225+39 = 1264
Yes: 1225 = 352
