4.4=k\times 8
Calculate 2 to the power of 3 and get 8.
k\times 8=4.4
Swap sides so that all variable terms are on the left hand side.
k=\frac{4.4}{8}
Divide both sides by 8.
k=\frac{44}{80}
Expand \frac{4.4}{8} by multiplying both numerator and the denominator by 10.
k=\frac{11}{20}
Reduce the fraction \frac{44}{80} to lowest terms by extracting and canceling out 4.
