16=x\times 1.6\times \frac{1}{10000000000000000000}
Calculate 10 to the power of -19 and get \frac{1}{10000000000000000000}.
16=x\times \frac{1}{6250000000000000000}
Multiply 1.6 and \frac{1}{10000000000000000000} to get \frac{1}{6250000000000000000}.
x\times \frac{1}{6250000000000000000}=16
Swap sides so that all variable terms are on the left hand side.
x=16\times 6250000000000000000
Multiply both sides by 6250000000000000000, the reciprocal of \frac{1}{6250000000000000000}.
x=100000000000000000000
Multiply 16 and 6250000000000000000 to get 100000000000000000000.
