Question

Daca a =0,(6) si b=0,0(6) atunci : raportul numerelor a si b este... ? Cat la suta reprezinta b din a ?

Answer 1

a= 0,(6)= 6/9= 2/3

b= 0,0(6)= 6/90= 2/30= 1/15

a/b=2/3/1/15= 2/3 * 15/1= 2*5=10

p% din a =b

p/100 * 2/3 = 1/15

p/50 * 1/3=1/15

p/50= 1/15/1/3

p/50= 1/15 * 3/1

p/50= 1/5

p=50/5=10%
