Question

(x-2/3):2/5=7/10

 

Answer 1

\(\left(x-\dfrac{2}{3}\right):\dfrac{2}{5}=\dfrac{7}{10}< =>\left(x-\dfrac{2}{3}\right)=\dfrac{7}{25}< =>x=\dfrac{71}{75}\)

Answer 2

=>x-2/3=7/10*2/5=14/50=7/25

=>x=7/25+2/3=21/75+50/75=71/75

Answer 3

\(\left(x-\dfrac{2}{3}\right):\dfrac{2}{5}=\dfrac{7}{10}\)

\(x-\dfrac{2}{3}=\dfrac{14}{50}\)

\(x=\dfrac{71}{75}\)
