\(x\times2+x\times\frac{1}{5}=1\frac{3}{5}\)

\(x\times\left(2+\frac{1}{5}\right)=\frac{8}{5}\)

\(x\times\frac{11}{5}=\frac{8}{5}\)

\(x=\frac{8}{5}\div\frac{11}{5}\)

\(x=\frac{8}{11}\)

\(\Rightarrow x.\left(2+\frac{1}{5}\right)=\frac{8}{5}\)

\(\Rightarrow\frac{11}{5}x=\frac{8}{5}\)

\(\Rightarrow x=\frac{8}{11}\)

1 + 1 =  2

2 + 3= 5

6 + 6 = 12  

Tìm x:

X + 3,68 = 4,035

X           = 4,035 - 3,68

X           = 0,355

5,0165 : X = 5

            X  = 5,0165 : 5

            X = 1,0033

Ủng hộ nha! :)      

Bài 1 :

1 + 1 = 2

2 + 3 = 5

6 + 6 = 12

Bài 2 :

x + 3,68 = 4,035

x           = 4,035 - 3,68

x            = 0,35

5,0165 : x = 5

              x = 5,0165 : 5

              x = 1.0033

không sao đâu

\(3\frac{3}{4}\times4=\frac{3\times4+3}{4}\times4=\frac{15}{4}\times4=\frac{15\times4}{4}=15\)

\(4\frac{3}{2}\div1\frac{1}{2}=\frac{4\times2+3}{2}\div\frac{1\times2+1}{2}=\frac{11}{2}\div\frac{3}{2}=\frac{11}{2}\times\frac{2}{3}=\frac{11}{3}\)
