\(x+\frac{3}{4}=\frac{1}{2}.\frac{2}{3}\)
\(x+\frac{3}{4}=\frac{2}{6}\)
\(x=\frac{2}{6}-\frac{3}{4}\)
\(x=\frac{-5}{12}\)
x+3/4=1/2.2/3
x+3/4=1/3
x=1/3-3/4
x=-5/12
k mik nhoa!!!!!!!!!!!!!!!!!
=> x + 1/2 = 5/6 + 3/4
=> x + 1/2 = 19/12
=> x = 19/12 - 1/2
=> x = 13/12
Vậy x = 13/12
Tk mk nha
a X+1/2-3/4=5/6 suy ra : Mỉnh phải đi ngủ rồi mai mình giải tiếp cho nhé
X+1/2=5/6+3/4
X+1/2=19/12
X=19/12-1/2
X=13/12
\(a,\frac{5}{6}+x\)x \(\frac{3}{4}=3\)
\(x\)x \(\frac{3}{4}=3-\frac{5}{6}\)
\(x\)x \(\frac{3}{4}=\frac{13}{6}\)
\(x=\frac{13}{6}:\frac{3}{4}\)
\(x=\frac{26}{9}\)
b, \(5\frac{1}{6}-x:\frac{3}{4}=\frac{2}{3}\)
\(\frac{31}{6}-x:\frac{3}{4}=\frac{2}{3}\)
\(x:\frac{3}{4}=\frac{31}{6}-\frac{2}{3}\)
\(x:\frac{3}{4}=\frac{9}{2}\)
\(x=\frac{9}{2}\)x \(\frac{3}{4}\)
\(x=\frac{27}{8}\)
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
\(x\cdot\frac{1}{3}:\frac{2}{5}=\frac{4}{3}\)
\(\Rightarrow x\cdot\frac{1}{3}=\frac{4}{3}\cdot\frac{2}{5}\)
\(\Rightarrow x\cdot\frac{1}{3}=\frac{8}{15}\)
\(\Rightarrow x=\frac{8}{15}:\frac{1}{3}\)
\(\Rightarrow x=\frac{8}{5}\)
Vậy x=........
\(x.\frac{1}{3}:\frac{2}{5}=\frac{4}{3}\)
\(x.\frac{1}{3}=\frac{4}{3}x\frac{2}{5}=\frac{8}{15}\)
\(x=\frac{8}{15}:\frac{1}{3}=\frac{8}{5}\)
học tốt
\(x+3\frac{1}{2}=\frac{1}{2}\)
\(x=\frac{1}{2}-3\frac{1}{2}\)
\(x=-3\)
\(2\frac{1}{2}-x=1\frac{2}{3}\)
\(x=2\frac{1}{2}-1\frac{2}{3}\)
\(x=\frac{5}{6}\)
\(\frac{3}{2}-x=\frac{1}{2}\)
\(x=\frac{3}{2}-\frac{1}{2}\)
\(x=\frac{2}{2}\)
\(x=1\)
Vậy \(x=1\)
3/2 - x = 1/2
x = 3/2 - 1/2
x = 2/2 hoặc 1
k đúng cho bạn nhé
\(x+\frac{2}{3}=3\frac{1}{3}\)
\(x=3\frac{1}{3}-\frac{2}{3}\)
\(x=\frac{8}{3}=2\frac{2}{3}\)
\(x+\frac{2}{3}=3\frac{1}{3}\)
\(x+\frac{2}{3}=\frac{10}{3}\)
\(x=\frac{10}{3}-\frac{2}{3}\)
\(x=\frac{7}{3}\)
