Đã có 3 câu trả lời lận, sao còn lặp lại :/?

\(a,\frac{22}{5}\div x=\frac{44}{5}\div\frac{5}{2}\)

\(\Rightarrow\frac{22}{5}\div x=\frac{88}{25}\)

\(\Rightarrow x=\frac{5}{4}\)

Thank you kim thạc trân for the amazing help!!!!!!!!

a)\(\frac{22}{5}:x=\frac{44}{5}:\frac{5}{2}=\frac{44}{5}.\frac{2}{5}=\frac{84}{25}\)

\(\Rightarrow x=\frac{22}{5}:\frac{84}{25}=\frac{22}{5}.\frac{25}{84}=\frac{55}{42}\)

b) \(8,35x+6,65x=45\)

\(\Rightarrow\left(8,35+6,65\right)x=45\Rightarrow15x=45\)

\(\Rightarrow x=45:15=3\)

\(a,\frac{22}{5}\div x=\frac{44}{5}\div\frac{5}{2}\)

\(\Rightarrow\frac{22}{5}\div x=\frac{88}{25}\)

\(\Rightarrow x=\frac{5}{4}\)

\(b,8,35\times x+6,65\times x=45\)

\(\Rightarrow x\times\left(8,35+6,65\right)=45\)

\(\Rightarrow x\times15=45\)

\(\Rightarrow x=3\)

SAO K CÓ ĐỀ BÀI VẬY BẠN

A) \(\frac{4}{5}\)x\( y\)=\(\frac{5}{7}:\frac{3}{14}=\frac{10}{3}\)

\(\Rightarrow y=\frac{10}{3}:\frac{4}{5}=\frac{10}{3}.\frac{5}{4}=\frac{25}{6}\)

B) \(\Rightarrow\frac{22}{5}:y=\frac{44}{5}:\frac{5}{2}=\frac{44}{5}.\frac{2}{5}=\frac{88}{25}\)

\(\Rightarrow y=\frac{22}{5}:\frac{88}{25}=\frac{22}{5}.\frac{25}{88}=\frac{5}{4}\)

a: =13/26*9/18*2/3=2/3*1/4=2/12=1/6

b: =44/22*5/15*3/2=2*1/3*3/2=2*1/2=1

a)\(x:\frac{9}{22}=44\)                                    b)\(x:\frac{5}{11}=33\)                           c)\(x:\frac{4}{33}=22\)

 \(x\)     \(=44\times\frac{9}{22}\)                        \(x\)       \(=33\times\frac{5}{11}\)                \(x\)       \(=22\times\frac{4}{33}\)    

   \(x\)      \(=18\)                                    \(x\)         \(=15\)                          \(x\)        \(=\frac{8}{3}\)

A) X : 9/22 = 44

              X=44x9/22

              X=18

B) X : 5/11 = 33

              X=33x5/11

              X=15

C) X : 4/33 = 22

              X=22x4/33

              X=8/3

\(x:\frac{9}{22}=44\)

\(x=44X\frac{9}{22}\)

\(x=18\)

vậy X = 18

\(x:\frac{5}{11}=33\)

\(x=33X\frac{5}{11}\)

\(x=15\)

vậy X = 15

\(x:\frac{4}{33}=22\)

\(x=22X\frac{4}{33}\)

\(x=\frac{8}{3}\)

vậy X = \(\frac{8}{3}\)
