\frac{0.07}{0.1}=\frac{x-0.38}{0.58-0.5}
Subtract 0.38 from 0.45 to get 0.07.
\frac{7}{10}=\frac{x-0.38}{0.58-0.5}
Expand \frac{0.07}{0.1} by multiplying both numerator and the denominator by 100.
\frac{7}{10}=\frac{x-0.38}{0.08}
Subtract 0.5 from 0.58 to get 0.08.
\frac{7}{10}=\frac{x}{0.08}+\frac{-0.38}{0.08}
Divide each term of x-0.38 by 0.08 to get \frac{x}{0.08}+\frac{-0.38}{0.08}.
\frac{7}{10}=\frac{x}{0.08}+\frac{-38}{8}
Expand \frac{-0.38}{0.08} by multiplying both numerator and the denominator by 100.
\frac{7}{10}=\frac{x}{0.08}-\frac{19}{4}
Reduce the fraction \frac{-38}{8} to lowest terms by extracting and canceling out 2.
\frac{x}{0.08}-\frac{19}{4}=\frac{7}{10}
Swap sides so that all variable terms are on the left hand side.
\frac{x}{0.08}=\frac{7}{10}+\frac{19}{4}
Add \frac{19}{4} to both sides.
\frac{x}{0.08}=\frac{14}{20}+\frac{95}{20}
Least common multiple of 10 and 4 is 20. Convert \frac{7}{10} and \frac{19}{4} to fractions with denominator 20.
\frac{x}{0.08}=\frac{14+95}{20}
Since \frac{14}{20} and \frac{95}{20} have the same denominator, add them by adding their numerators.
\frac{x}{0.08}=\frac{109}{20}
Add 14 and 95 to get 109.
x=\frac{109}{20}\times 0.08
Multiply both sides by 0.08.
x=\frac{109}{20}\times \frac{2}{25}
Convert decimal number 0.08 to fraction \frac{8}{100}. Reduce the fraction \frac{8}{100} to lowest terms by extracting and canceling out 4.
x=\frac{109\times 2}{20\times 25}
Multiply \frac{109}{20} times \frac{2}{25} by multiplying numerator times numerator and denominator times denominator.
x=\frac{218}{500}
Do the multiplications in the fraction \frac{109\times 2}{20\times 25}.
x=\frac{109}{250}
Reduce the fraction \frac{218}{500} to lowest terms by extracting and canceling out 2.
