\frac{2.56}{1.28}\geq c
Divide both sides by 1.28. Since 1.28 is positive, the inequality direction remains the same.
\frac{256}{128}\geq c
Expand \frac{2.56}{1.28} by multiplying both numerator and the denominator by 100.
2\geq c
Divide 256 by 128 to get 2.
c\leq 2
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
