If you define a rectangular number as a number which is the product of two consecutive integers, none of them qualify.
All three of them are.
The smallest consecutive three numbers that total 120 are... 39, 40 & 41.
Thrice with a remainder of 3
120-159 in stone = -39
120 over 39 in simplest form = 40/13 or 31/13
It is: 3
It is 1560
3.5294
It is: 120 to 13
47
69+39 degrees happy now?
It is: 3
120 (assuming the pattern is x3, +1, x3, +1...)
