30\times 10^{-6}x=2\times 10^{-7}\times 4,5
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
30\times \frac{1}{1000000}x=2\times 10^{-7}\times 4,5
Calculate 10 to the power of -6 and get \frac{1}{1000000}.
\frac{3}{100000}x=2\times 10^{-7}\times 4,5
Multiply 30 and \frac{1}{1000000} to get \frac{3}{100000}.
\frac{3}{100000}x=2\times \frac{1}{10000000}\times 4,5
Calculate 10 to the power of -7 and get \frac{1}{10000000}.
\frac{3}{100000}x=\frac{1}{5000000}\times 4,5
Multiply 2 and \frac{1}{10000000} to get \frac{1}{5000000}.
\frac{3}{100000}x=\frac{9}{10000000}
Multiply \frac{1}{5000000} and 4,5 to get \frac{9}{10000000}.
x=\frac{9}{10000000}\times \frac{100000}{3}
Multiply both sides by \frac{100000}{3}, the reciprocal of \frac{3}{100000}.
x=\frac{3}{100}
Multiply \frac{9}{10000000} and \frac{100000}{3} to get \frac{3}{100}.
