Explanation:
This problem is quite straightforward since we are at liberty to choose any number at gives the required results.
Say we have the number 2.7 and the task is to look for two digit whose sum will give the number, we can simply divide 2.7 by 2
2.7 /2 = 1.35
Since we need a 2 digit number let us round up to the nearest tenth
1.4
To get the second number
2.7-1.4= 1.3
Hence the two digit numbers that add up to 2.7 are
1.4 and 1.3
The three digits numbers can be gotten by Dividing 2.7 by 2= 1.35
Which is a three digit number
The numbers are 1.35 and 1.35
Hence 1.35+1.35 = 2.7
