3k=4.8+0.6
Add 0.6 to both sides.
3k=5.4
Add 4.8 and 0.6 to get 5.4.
k=\frac{5.4}{3}
Divide both sides by 3.
k=\frac{54}{30}
Expand \frac{5.4}{3} by multiplying both numerator and the denominator by 10.
k=\frac{9}{5}
Reduce the fraction \frac{54}{30} to lowest terms by extracting and canceling out 6.
