\(y+1\frac{21}{22}=2\frac{43}{44}\Rightarrow y+\frac{43}{22}=\frac{131}{44}\Rightarrow y=\frac{131}{44}-\frac{86}{44}\Rightarrow y=\frac{45}{44}\)
\(y+1\frac{21}{22}=2\frac{43}{44}\)
\(y+\frac{43}{22}=\frac{131}{44}\)
y \(=\)\(\frac{131}{44}-\frac{43}{22}=\frac{45}{44}\)
1, (y-2/5):4/15=5/8
(y-2/5)=5/8.4/15
y-2/5=1/6
=>y=1/6+2/5
=>y=17/30
vậy y=17/30
\(\frac{22}{9}x-\frac{1}{3}=\frac{5}{9}\)
\(\Rightarrow\frac{22}{9}x=\frac{5}{9}+\frac{1}{3}\)
\(\Rightarrow\frac{22}{9}x=\frac{8}{9}\)
\(\Rightarrow x=\frac{8}{9}:\frac{22}{9}=\frac{8}{9}x\frac{9}{22}\)
\(\Rightarrow x=\frac{4}{11}\)
\(\frac{22}{9}x-\frac{1}{3}=\frac{5}{9}\)
\(\frac{22}{9}x=\frac{5}{9}+\frac{1}{3}\)
\(\frac{22}{9}x=\frac{8}{9}\)
\(x=\frac{8}{9}:\frac{22}{9}=\frac{4}{11}\)
vậy \(x=\frac{4}{11}\)
\(\frac{22}{9}-x.\frac{1}{3}=\frac{5}{9}\)
\(\Rightarrow\frac{22}{9}-\frac{x}{3}=\frac{5}{9}\)
\(\Rightarrow\frac{x}{3}=\frac{22}{9}-\frac{5}{9}\)
\(\Rightarrow\frac{x}{3}=\frac{17}{9}\)
\(\Rightarrow\frac{3.x}{9}=\frac{17}{9}\Rightarrow3.x=17\Rightarrow x=\frac{17}{3}\)
Chúc bn hc giỏi!
2 nhé !
Chúc bạn học tốt ^-^
\(\frac{55}{22}+\frac{44}{22}\)
\(=\frac{55+44}{22}\)
\(=\frac{99}{22}\)
