\frac{0.13}{15-10}=\frac{x-1}{3.4}
Subtract 1 from 1.13 to get 0.13.
\frac{0.13}{5}=\frac{x-1}{3.4}
Subtract 10 from 15 to get 5.
\frac{13}{500}=\frac{x-1}{3.4}
Expand \frac{0.13}{5} by multiplying both numerator and the denominator by 100.
\frac{13}{500}=\frac{x}{3.4}+\frac{-1}{3.4}
Divide each term of x-1 by 3.4 to get \frac{x}{3.4}+\frac{-1}{3.4}.
\frac{13}{500}=\frac{x}{3.4}+\frac{-10}{34}
Expand \frac{-1}{3.4} by multiplying both numerator and the denominator by 10.
\frac{13}{500}=\frac{x}{3.4}-\frac{5}{17}
Reduce the fraction \frac{-10}{34} to lowest terms by extracting and canceling out 2.
\frac{x}{3.4}-\frac{5}{17}=\frac{13}{500}
Swap sides so that all variable terms are on the left hand side.
\frac{x}{3.4}=\frac{13}{500}+\frac{5}{17}
Add \frac{5}{17} to both sides.
\frac{x}{3.4}=\frac{221}{8500}+\frac{2500}{8500}
Least common multiple of 500 and 17 is 8500. Convert \frac{13}{500} and \frac{5}{17} to fractions with denominator 8500.
\frac{x}{3.4}=\frac{221+2500}{8500}
Since \frac{221}{8500} and \frac{2500}{8500} have the same denominator, add them by adding their numerators.
\frac{x}{3.4}=\frac{2721}{8500}
Add 221 and 2500 to get 2721.
x=\frac{2721}{8500}\times 3.4
Multiply both sides by 3.4.
x=\frac{2721}{8500}\times \frac{17}{5}
Convert decimal number 3.4 to fraction \frac{34}{10}. Reduce the fraction \frac{34}{10} to lowest terms by extracting and canceling out 2.
x=\frac{2721\times 17}{8500\times 5}
Multiply \frac{2721}{8500} times \frac{17}{5} by multiplying numerator times numerator and denominator times denominator.
x=\frac{46257}{42500}
Do the multiplications in the fraction \frac{2721\times 17}{8500\times 5}.
x=\frac{2721}{2500}
Reduce the fraction \frac{46257}{42500} to lowest terms by extracting and canceling out 17.
