30+0.7m-0.6m>31
Subtract 0.6m from both sides.
30+0.1m>31
Combine 0.7m and -0.6m to get 0.1m.
0.1m>31-30
Subtract 30 from both sides.
0.1m>1
Subtract 30 from 31 to get 1.
m>\frac{1}{0.1}
Divide both sides by 0.1. Since 0.1 is positive, the inequality direction remains the same.
m>10
Expand \frac{1}{0.1} by multiplying both numerator and the denominator by 10. Anything divided by one gives itself.
