314\times \frac{1}{10000000}=0.1x
Calculate 10 to the power of -7 and get \frac{1}{10000000}.
\frac{157}{5000000}=0.1x
Multiply 314 and \frac{1}{10000000} to get \frac{157}{5000000}.
0.1x=\frac{157}{5000000}
Swap sides so that all variable terms are on the left hand side.
x=\frac{\frac{157}{5000000}}{0.1}
Divide both sides by 0.1.
x=\frac{157}{5000000\times 0.1}
Express \frac{\frac{157}{5000000}}{0.1} as a single fraction.
x=\frac{157}{500000}
Multiply 5000000 and 0.1 to get 500000.
