4.9\leq 20m
Subtract 0.1 from 5 to get 4.9.
20m\geq 4.9
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
m\geq \frac{4.9}{20}
Divide both sides by 20. Since 20 is positive, the inequality direction remains the same.
m\geq \frac{49}{200}
Expand \frac{4.9}{20} by multiplying both numerator and the denominator by 10.
