c- 8.47 < 1 .52

The statement "c- 8.47 < 1 .52" is not mathematically valid as there is a space between the digits 1 and .52. Assuming there's no space error, let's analyze it:

To compare the numbers, we consider the decimal values. Thus, 8.47 is greater than 1.52.

Therefore, the correct inequality will be:
c - 8.47 < 1.52
