Lớp học online hay j mà lắm giáo viên thế🤔🤔 Lớp học của tri thức à?
9/4 - y * 5/6 = 1/2 + 2/3
9/4 - y * 5/6 = 7/6
y * 5/6 = 9/4 - 7/6
y * 5/6 = 13/12
y = 13/12 : 5/6
y = 13/10
K mk nha
Mk cảm ơn bạn nhiều
Thank you very much

9/4 - y + 5/6 = 1/2 + 2/3
9/4 - y + 5/6 = 7/6
9/4 - y = 7/6 - 5/6
9/4 - y = 1/3
y = 9/4 - 1/3
y = 23/12
\(\frac{9}{4}-y\cdot\frac{5}{6}=\frac{1}{2}+\frac{2}{3}\)
\(\Rightarrow\frac{9}{4}-y\cdot\frac{5}{6}=\frac{7}{6}\)
\(\Rightarrow\frac{9}{4}-y=\frac{7}{6}:\frac{5}{6}\)
\(\Rightarrow\frac{9}{4}-y=\frac{7}{5}\)
\(\Rightarrow y=\frac{9}{4}-\frac{7}{5}=\frac{17}{20}\)
9/4 - y . 5/6 = 1/2 +2/3
9/4 - y . 5/6 = 7/6
9/4 - y = 7/6 : 5/6
9/4 - y = 7/5
y = 9/4 - 7/5
y = 17/20
\(\frac{9}{4}-y\times\frac{5}{6}=\frac{1}{2}+\frac{2}{3}\)
\(\frac{9}{4}-y\times\frac{5}{6}=\frac{7}{6}\)
\(y\times\frac{5}{6}=\frac{9}{4}-\frac{7}{6}\)
\(y\times\frac{5}{6}=\frac{13}{12}\)
\(y=\frac{13}{12}:\frac{5}{6}\)
\(y=\frac{13}{10}\)
\(\frac{9}{4}-y\times\frac{5}{6}=\frac{1}{2}+\frac{2}{3}\)
\(\frac{9}{4}-y\times\frac{5}{6}=\frac{7}{6}\)
\(y\times\frac{5}{6}=\frac{9}{4}-\frac{7}{6}\)
\(y\times\frac{5}{6}=\frac{13}{12}\)
\(y=\frac{13}{12}:\frac{5}{6}\)
\(y=\frac{13}{10}\)
\(\dfrac{8}{9}:\dfrac{3}{7}=\dfrac{56}{27}\\ \dfrac{8}{9}+\dfrac{2}{5}=\dfrac{58}{45}\\ \dfrac{7}{8}-\dfrac{1}{3}=\dfrac{13}{24}\\ \dfrac{3}{10}\times\dfrac{1}{6}=\dfrac{1}{20}\\ 1\dfrac{2}{7}+6\dfrac{5}{6}=\dfrac{9}{7}+\dfrac{41}{6}=\dfrac{341}{42}\\ 5\dfrac{3}{4}-\dfrac{1}{5}=\dfrac{23}{4}-\dfrac{1}{5}=\dfrac{111}{20}\\ 6\dfrac{2}{9}:4\dfrac{7}{10}=\dfrac{56}{9}:\dfrac{47}{10}=\dfrac{560}{423}\\ \dfrac{5}{3}+\dfrac{3}{2}-\dfrac{7}{6}=2\)
\(\frac{9}{4}-y.\frac{5}{6}=\frac{1}{2}+\frac{2}{3}\)
\(\frac{9}{4}-y.\frac{5}{6}=\frac{7}{6}\)
\(y.\frac{5}{6}=\frac{9}{4}-\frac{7}{6}\)
\(y.\frac{5}{6}=\frac{13}{12}\)
\(y=\frac{13}{12}:\frac{5}{6}\)
\(y=\frac{13}{10}\)
