10/14=x/7
Urgent va roggg​

Answer 1

o sa le notez cu a) , b) si asa mai departe pentru a nu le incurca

a) 8/x  = 4/ 3    

x=  8 * 3 / 4

x= 24 / 4  = 6

b) 3/7 = x / 28

x = 3 * 28 / 7

x = 84 / 7 = 12

c) 15 / 18 = 5 / x

x = 18  * 5  / 15

x = 90 / 15 = 4

d) x/6 = 2

x = 6 * 2 = 12

e) 7 = x/ 3

x = 7 * 3  = 21

f) 9/x = 3

x = 9 / 3 = 3

g) 6 = 4/x

x= 4/ 6 ( simplificam cu 2 )

x = 2/ 3

h) 8/x = 4/ 3

x= 8 * 3  / 4

x= 24 / 4 = 6

i) 10/14 = x / 7

x= 10* 7 / 14

x= 70 / 14  = 5
