Expand \frac{34.6}{4} by multiplying both numerator and the denominator by 10.
\frac{173}{20}\times 0.6-2.3\times 4.9=32-a-21.1+10.6
Reduce the fraction \frac{346}{40} to lowest terms by extracting and canceling out 2.
\frac{173}{20}\times \frac{3}{5}-2.3\times 4.9=32-a-21.1+10.6
Convert decimal number 0.6 to fraction \frac{6}{10}. Reduce the fraction \frac{6}{10} to lowest terms by extracting and canceling out 2.
\frac{173\times 3}{20\times 5}-2.3\times 4.9=32-a-21.1+10.6
Multiply \frac{173}{20} times \frac{3}{5} by multiplying numerator times numerator and denominator times denominator.
\frac{519}{100}-2.3\times 4.9=32-a-21.1+10.6
Do the multiplications in the fraction \frac{173\times 3}{20\times 5}.
\frac{519}{100}-11.27=32-a-21.1+10.6
Multiply 2.3 and 4.9 to get 11.27.
\frac{519}{100}-\frac{1127}{100}=32-a-21.1+10.6
Convert decimal number 11.27 to fraction \frac{1127}{100}.
\frac{519-1127}{100}=32-a-21.1+10.6
Since \frac{519}{100} and \frac{1127}{100} have the same denominator, subtract them by subtracting their numerators.
\frac{-608}{100}=32-a-21.1+10.6

-\frac{152}{25}=32-a-21.1+10.6
Reduce the fraction \frac{-608}{100} to lowest terms by extracting and canceling out 4.
-\frac{152}{25}=10.9-a+10.6
Subtract 21.1 from 32 to get 10.9.
-\frac{152}{25}=21.5-a
Add 10.9 and 10.6 to get 21.5.
21.5-a=-\frac{152}{25}
Swap sides so that all variable terms are on the left hand side.
-a=-\frac{152}{25}-21.5
Subtract 21.5 from both sides.
-a=-\frac{152}{25}-\frac{43}{2}
Convert decimal number 21.5 to fraction \frac{215}{10}. Reduce the fraction \frac{215}{10} to lowest terms by extracting and canceling out 5.
-a=-\frac{304}{50}-\frac{1075}{50}
Least common multiple of 25 and 2 is 50. Convert -\frac{152}{25} and \frac{43}{2} to fractions with denominator 50.
-a=\frac{-304-1075}{50}
Since -\frac{304}{50} and \frac{1075}{50} have the same denominator, subtract them by subtracting their numerators.
-a=-\frac{1379}{50}
Subtract 1075 from -304 to get -1379.
a=\frac{1379}{50}
Multiply both sides by -1.
