Question

tìm x

Answer 1

\(Xx\dfrac{4}{7}=\dfrac{19}{18}\)

\(X=\dfrac{19}{18}:\dfrac{4}{7}\)

\(X=\dfrac{132}{72}\)

Answer 2

\(x\times\dfrac{4}{7}=\dfrac{19}{18}\\ x=\dfrac{19}{18}\div\dfrac{4}{7}\\ x=\dfrac{133}{72}\)

Answer 3

X x 4/7=15/18+4/18

X x 4/7=19/18

X=19/18:4/7

X=19/18x7/4

X=133/72

Answer 4

b) \(x\times\dfrac{4}{7}=\dfrac{5}{6}+\dfrac{2}{9}\)

    \(x\times\dfrac{4}{7}=\dfrac{19}{18}\)

    \(x=\dfrac{19}{18}:\dfrac{4}{7}\)

     \(x=\dfrac{19}{18}\times\dfrac{7}{4}\)

   \(x=\dfrac{133}{72}\)
