\frac{16}{8}=\frac{x}{3.2}
Expand \frac{1.6}{0.8} by multiplying both numerator and the denominator by 10.
2=\frac{x}{3.2}
Divide 16 by 8 to get 2.
\frac{x}{3.2}=2
Swap sides so that all variable terms are on the left hand side.
x=2\times 3.2
Multiply both sides by 3.2.
x=6.4
Multiply 2 and 3.2 to get 6.4.
