Răspuns:

Explicație pas cu pas:

$\frac{x}{y} = \frac{5}{13}$

a)

$\frac{x + y}{y} = \frac{5 + 13}{13} = \frac{18}{13}$

b)

$\frac{x}{y + x} = \frac{5}{13 + 5} = \frac{5}{18}$

c)

$\frac{y - x}{x} = \frac{13 - 5}{5} = \frac{8}{5}$

Answer 2

Răspuns:

x/y=5/13

a)

(x+y)/y=(5+13)/13=18/13

b)

x/(y+x)=5/(13+5)=5/18

c)

(y-x)/x=(13-5)/5=8/5
