= 3/4 + 5/6 x 3/2 + 1/5
= 3/4 + 5/4 + 1/5
= 15/20 + 25/20 + 4/20
= 44/20
= 11/5
TL
\(\frac{3}{4}+\frac{5}{6}:\frac{2}{3}+\frac{1}{5}\)
\(=\frac{3}{4}+\frac{5}{4}+\frac{1}{5}\)
\(=\frac{11}{5}\)
nhaaaaaaa
HT
\(\frac{3}{4}+\frac{5}{6}\div\frac{2}{3}+\frac{1}{5}\)
\(=\frac{3}{4}+\frac{5}{6}\times\frac{3}{2}+\frac{1}{5}\)
\(=\frac{3}{4}+\frac{5}{4}+\frac{1}{5}\)
\(=2+\frac{1}{5}\)
\(=\frac{11}{5}\)
\(=\dfrac{3}{4}+\dfrac{5}{6}.\dfrac{3}{2}+\dfrac{1}{5}\)
\(=\dfrac{3}{4}+\dfrac{5}{4}+\dfrac{1}{5}=2+\dfrac{1}{5}=\dfrac{11}{5}\)
