Question

x * 4/8 = 3/11

1/9 + x = 1 - 3/18

mọi người làm đầy đủ phép tính nhé

Answer 1

\(x\times\frac{4}{8}=\frac{3}{11}\)

=> \(x=\frac{3}{11}:\frac{4}{8}\)

=> \(x=\frac{3}{11}\times\frac{8}{4}=\frac{3}{11}\times2=\frac{6}{11}\)

Cách 1 : \(\frac{1}{9}+x=1-\frac{3}{18}\)

=> \(\frac{2}{18}+\frac{18x}{18}=\frac{18}{18}-\frac{3}{18}\)

=> 2 + 18x = 18 - 3

=> 18x = 18 - 3 - 2

=> 18x = 13

=> x = \(\frac{13}{18}\)

Cách 2 : \(\frac{1}{9}+x=1-\frac{3}{18}\)

=> \(\frac{1}{9}+x=\frac{18}{18}-\frac{3}{18}=\frac{15}{18}\)

=> \(\frac{1}{9}+x=\frac{5}{6}\)

=> \(x=\frac{5}{6}-\frac{1}{9}=\frac{15}{18}-\frac{2}{18}=\frac{13}{18}\)

Answer 2

X x 4/8 = 3/11                                  

X          =3/11:4/8

X          = 6/11

1/9 + x = 1-3/18

1/9 + x = 5/6

        x = 5/6 - 1/9

        x = 13/18 

k cho mình nhé.

Answer 3

X*4/8=3/11

X=3/11:4/8

X=24/44=6/11

1/9+x=1-3/18

1/9+x=15/18

X=15/18-1/9

X=13/18

tk nha

Answer 4

x* 4\8=3\11x=3\11: 4\8

x=6\11
