1. Find the other number:
- Let the unknown number be 'x'.
- The sum of the two numbers is given as 11/12.
- So, 5/12 + x = 11/12
- To find x, subtract 5/12 from both sides:
- x = 11/12 - 5/12
- x = (11 - 5) / 12
- x = 6/12
- Simplify the fraction:
- x = 1/2
2. Find by how much it is less:
- We need to compare the two numbers: 5/12 and 1/2 (which is 6/12).
- The question asks "by how much is it less?" This implies we need to find the difference between the larger number and the smaller number.
- Difference = Larger number - Smaller number
- Difference = 6/12 - 5/12
- Difference = (6 - 5) / 12
- Difference = 1/12
Answer: The other number is 1/2. It is 1/12 less than the first number.
