Question

Tìm x:  (x-7/18).15/27=10/27

Answer 1

\(\left(x-\dfrac{7}{18}\right)\cdot\dfrac{15}{27}=\dfrac{10}{27}\\ \Leftrightarrow x-\dfrac{7}{18}=\dfrac{2}{3}\\ \Leftrightarrow x=\dfrac{19}{18}\)

Answer 2

=10/27

Answer 3

(x-7/18).15/27 = 10/27

<=> (x-7/18 ) = 10/27:15/27

<=> (x-7/18) = 10/27.27/15

<=> x-7/18 = 2/3

<=> x = 2/3 + 7/18

<=> x = 19/18

 

Answer 4

\(\left(x-\dfrac{7}{18}\right).\dfrac{15}{27}=\dfrac{10}{27}\)

\(\Rightarrow x-\dfrac{7}{18}=\dfrac{10}{27}:\dfrac{15}{27}\)

\(\Rightarrow x-\dfrac{7}{18}=\dfrac{2}{3}\)

\(\Rightarrow x=\dfrac{2}{3}+\dfrac{7}{18}\)

\(\Rightarrow x=\dfrac{19}{18}\)

Answer 5

19/18
