0 and 27, 1 and 28, 2 and 29, 3 and 30.
28 2 27 3 29 1 etc...
It is 2+28 = 30
1 + 29 = 30 2 + 28 = 30 3 + 27 = 30 4 + 26 = 30 etc...
54/56 = (2×27)/(2×28) = 27/28
The Least Common Multiple of 2, 27, 28 is: 756
The answer is 30C4 = 30*29*28*27/(4*3*2*1) = 27,405
If you take four consecutive numbers, for example, 27, 28, 29, and 30, then 27/3 = 9, 28/3 = 9 remainder 1, 29/3 = 9 remainder 2, 30/3 = 10. Therefore, the greatest remainder you can get when dividing by 3 is 2.
30
If you mean 2 into 28 then it is 14 times
2425 27 + (30 x 80) - 2 30 x 80 = 2400 2400 + 27 = 2427 2427 - 2 = 2425
The composite numbers from 2 - 30 are: 4, 6, 8, 9, 10, 12, 14, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28 and 30
