b) x:15=4:y=2:3​

Answer 1

Resposta:

A) (x, y) (2,3)

B) (x, y) (10,6)

Answer 2

a.

x/4 = y=6 = 1/2    

y/6 = 1/2

2y = 6

y = 6/2

y = 3

x/4 = 3/6

6x = 3 * 4

6x = 12

x = 12 / 6

x = 2

b)x/15=4/y=2/3

4/y = 2/3

2y = 3 * 4

2y = 12

y = 12 / 2  

y = 6

x/ 15 = 4 / 6

6x = 4 * 15

6x = 60

x = 60 / 6

x = 10......

espero que ajude!!!!!!!!!
