Question

Determine o valor de x e y em cada item a)x/4=y/6=1/2 b)x/15=4/y=2/3

Answer 1

Olá Jhennyfer, Boa noite!!!!!
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!!!!!!!!!
