c - 9 ╤ c - 3

Solution:

We are comparing two expressions: 'c - 9' and 'c - 3'.

• Since 'c' is a common part of both expressions, we can compare the subtrahends: 9 and 3.
• When subtracting from the same number 'c', subtracting a larger number (9) results in a smaller value than subtracting a smaller number (3). Therefore, 'c - 9' will always be less than 'c - 3'.

Comparison: c - 9 < c - 3
