Rút gọn rồi tính:

a) $\frac{16}{24}–\frac{1}{3}=\frac{2}{3}–\frac{1}{3}=\frac{2–1}{3}=\frac{1}{3}$     

b) $\frac{4}{5}–\frac{12}{60}=\frac{4}{5}–\frac{1}{5}=\frac{3}{5}$

Tính rồi rút gọn:

a) $\frac{17}{6}–\frac{2}{6}=\frac{17–2}{6}=\frac{15}{6}=\frac{5}{2}$             

b) $\frac{16}{15}–\frac{11}{15}=\frac{16–11}{15}=\frac{5}{15}=\frac{1}{3}$

c) $\frac{19}{12}–\frac{13}{12}=\frac{19–13}{12}=\frac{6}{12}=\frac{1}{2}$

\(\frac{1}{3}+\frac{1}{4}+\frac{1}{5}+\frac{4}{6}+\frac{9}{12}+\frac{16}{20}\)

\(=\frac{1}{3}+\frac{1}{4}+\frac{1}{5}+\frac{2}{3}+\frac{3}{4}+\frac{4}{5}\)

\(=\left(\frac{1}{3}+\frac{2}{3}\right)+\left(\frac{1}{4}+\frac{3}{4}\right)+\left(\frac{1}{5}+\frac{4}{5}\right)\)

\(=\frac{3}{3}+\frac{4}{4}+\frac{5}{5}\)

\(=1+1+1\)

\(=3\)

\(\dfrac{1}{3}+\dfrac{1}{4}+\dfrac{1}{5}+\dfrac{4}{6}+\dfrac{9}{12}+\dfrac{16}{20}\)

\(=\dfrac{1}{3}+\dfrac{1}{4}+\dfrac{1}{5}+\dfrac{2}{3}+\dfrac{3}{4}+\dfrac{4}{5}\)

\(=\left(\dfrac{1}{3}+\dfrac{2}{3}\right)+\left(\dfrac{1}{4}+\dfrac{3}{4}\right)+\left(\dfrac{1}{5}+\dfrac{4}{5}\right)\)

\(=\dfrac{3}{3}+\dfrac{4}{4}+\dfrac{5}{5}\)

\(=1+1+1=3\)

a) \(\frac{20}{16}-\frac{3}{4}=\frac{20}{16}-\frac{12}{16}=\frac{8}{16}=\frac{1}{2}\)

b) \(\frac{30}{45}-\frac{2}{5}=\frac{30}{45}-\frac{18}{45}=\frac{12}{45}=\frac{4}{15}\)

c) \(\frac{10}{12}-\frac{3}{4}=\frac{10}{12}-\frac{8}{12}=\frac{1}{12}\)

a) \(\frac{20}{16}-\frac{3}{4}=\frac{5}{4}-\frac{3}{4}=\frac{1}{2}\)

b) \(\frac{30}{45}-\frac{2}{5}=\frac{2}{3}-\frac{2}{5}=\frac{10}{15}-\frac{6}{15}=\frac{4}{15}\)

c) \(\frac{10}{12}-\frac{3}{4}=\frac{10}{12}-\frac{9}{12}=\frac{1}{12}\)

d) \(\frac{12}{9}-\frac{1}{4}=\frac{4}{3}-\frac{1}{4}=\frac{16}{12}-\frac{3}{12}=\frac{13}{12}\)
