\frac{9}{12}+\frac{10}{12}-\frac{15}{12}\approx 0.333333333
Least common multiple of 4 and 6 is 12. Convert \frac{3}{4}=0.75 and \frac{5}{6}\approx 0.833333333 to fractions with denominator 12.
\frac{9+10}{12}-\frac{15}{12}\approx 0.333333333
Since \frac{9}{12}=0.75 and \frac{10}{12}\approx 0.833333333 have the same denominator, add them by adding their numerators.
\frac{19}{12}-\frac{15}{12}\approx 0.333333333
Add 9 and 10 to get 19.
\frac{19-15}{12}\approx 0.333333333
Since \frac{19}{12}\approx 1.583333333 and \frac{15}{12}=1.25 have the same denominator, subtract them by subtracting their numerators.
\frac{4}{12}\approx 0.333333333
Subtract 15 from 19 to get 4.
\frac{1}{3}\approx 0.333333333
Reduce the fraction \frac{4}{12}\approx 0.333333333 to lowest terms by extracting and canceling out 4.
