\frac{16}{2}=\frac{z}{0,3}
Expand \frac{1,6}{0,2} by multiplying both numerator and the denominator by 10.
8=\frac{z}{0,3}
Divide 16 by 2 to get 8.
\frac{z}{0,3}=8
Swap sides so that all variable terms are on the left hand side.
z=8\times 0,3
Multiply both sides by 0,3.
z=2,4
Multiply 8 and 0,3 to get 2,4.
