Question

9,6-(1,(6)+2,(3))+1pe4-(0,25:0,1-0,4)

Answer 1

9,6=96/10=48/5
1,(6)=1 intreg 6/9 = 15/9 = 5/3
2,(3)=2 intregi 3/9 = 21/9 = 7/3
0,25=25/100=1/4
0,1=1/10
0,4=4/10=2/5

48/5-(5/3 + 7/3)+1/4 - (1/4 x 10 - 2/5)=
48/5 - 4 + 1/4 - (5/2 - 2/5)=
48/5 - 4 + 1/4 - (25-4)/10=
48/5 - 4 + 1/4 - 21/10=
Numitor comun 20
(48x4 - 80 + 5 - 42)/20=
(192-117)/20=
75/20=
15/4=
