Răspuns:

Explicație pas cu pas:

{[0,(6)-0,5]. 18 -0,75}: (5,05 – 1,45)​ =

= {[6/9 - 0,5]. 18 - 0,75}: (5,05 – 1,45) =

= {[6/9 - 5/10]. 18 - 75/100}: 3,6 =

= {[(6 · 10) /90 - (5 · 9) /90]. 18 - 75/100}: 3,6 =​​

= {[(60/90 - 45 /90]. 18 - 75/100}: 3,6 =

= {[(15 /90]. 18 - 75/100}: 3,6 =

= {[(1/6). 18 - 75/100}: 3,6 =

= {[(3 - 75/100}: 3,6 =

= {[(3 · 100)/100 - 75/100}: 3,6 =

= {[(300-75)/100}: 3,6 =

= {[(225)/100}: 36/10 =

​​= {[(225)/100} · 10/36 =

= 225/360 =

= 5/8
