\frac{4}{3}-\left(\frac{2}{4}+\frac{1}{4}\right)-\left(\frac{1}{8}+\frac{1}{16}\right)
Least common multiple of 2 and 4 is 4. Convert \frac{1}{2} and \frac{1}{4} to fractions with denominator 4.
\frac{4}{3}-\frac{2+1}{4}-\left(\frac{1}{8}+\frac{1}{16}\right)
Since \frac{2}{4} and \frac{1}{4} have the same denominator, add them by adding their numerators.
\frac{4}{3}-\frac{3}{4}-\left(\frac{1}{8}+\frac{1}{16}\right)
Add 2 and 1 to get 3.
\frac{16}{12}-\frac{9}{12}-\left(\frac{1}{8}+\frac{1}{16}\right)
Least common multiple of 3 and 4 is 12. Convert \frac{4}{3} and \frac{3}{4} to fractions with denominator 12.
\frac{16-9}{12}-\left(\frac{1}{8}+\frac{1}{16}\right)
Since \frac{16}{12} and \frac{9}{12} have the same denominator, subtract them by subtracting their numerators.
\frac{7}{12}-\left(\frac{1}{8}+\frac{1}{16}\right)
Subtract 9 from 16 to get 7.
\frac{7}{12}-\left(\frac{2}{16}+\frac{1}{16}\right)
Least common multiple of 8 and 16 is 16. Convert \frac{1}{8} and \frac{1}{16} to fractions with denominator 16.
\frac{7}{12}-\frac{2+1}{16}
Since \frac{2}{16} and \frac{1}{16} have the same denominator, add them by adding their numerators.
\frac{7}{12}-\frac{3}{16}
Add 2 and 1 to get 3.
\frac{28}{48}-\frac{9}{48}
Least common multiple of 12 and 16 is 48. Convert \frac{7}{12} and \frac{3}{16} to fractions with denominator 48.
\frac{28-9}{48}
Since \frac{28}{48} and \frac{9}{48} have the same denominator, subtract them by subtracting their numerators.
\frac{19}{48}
