6.8t<66.2-39
Subtract 39 from both sides.
6.8t<27.2
Subtract 39 from 66.2 to get 27.2.
t<\frac{27.2}{6.8}
Divide both sides by 6.8. Since 6.8 is positive, the inequality direction remains the same.
t<\frac{272}{68}
Expand \frac{27.2}{6.8} by multiplying both numerator and the denominator by 10.
t<4
Divide 272 by 68 to get 4.
