fds
$2 {2 {2 {?}^{?} }^{?} }^{?}$

Answer 2

a

x/8 = 3/6 = y/10

x/8 =  3/6

6 * x = 8 * 3

6x = 24

x = 24/6  = 4 *****  resposta

y/10 = 3/6

6 * y = 10 * 3

6y = 30

y = 30/6 = 5 **** resposta

b

x/12   = 5/15 = y/13

x/12 =5/15

15 * x = 12 * 5

15x = 60

x = 60/15  = 4 ***resposta

4/12 = y/13

12 * y = 13 * 4

12y = 52

y = 52/12 =4,3 ****resposta
