Question

Daca x/y = 2/3, aflati valoarea raportului 2x+y(totul)/x.
Ajutati-ma va rog!

Answer 1

x / y = 2 / 3 , ( 2x + y ) / x

------------------------------------------

x / 2 = y / 3 = K

x / 2 = K => x = 2 K

y / 3 = K => y = 3 K

⇒ ( 2 · 2 K + 3 K ) / 2 K =

= ( 4 K + 3 K ) / 2 K

= 7 K / 2 K

= 7 / 2

Answer 2

x/y = 2/3 = > x/2 = y/3 = k

x/2 = k => x = 2k

y/3 = k => y = 3k

(2x + y)/x =

= (2·2k + 3k)/2k

= (4k + 3k)/2k

= 7k/2k

= 7/2
