Question

Dupa ce a parcurs o cincime din lungimea unui drum,Vlad a constatat ca mai are de parcurs 22,5km pana sa ajunga la jumatatea drumului.Ce lungime are drumul?

Answer 1

$\frac{2}{10}+22,5= \frac{5}{10}$

$22,5= \frac{5}{10}- \frac{2}{10}$

[tex]22,5= \frac{3}{10} [/tex]

$\frac{1}{10} =22,5:3=7,5$

[tex] \frac{10}{10}=7,5*10=75 [/tex]

drumul are 75 km
