Question

6/15:{3,25:26*1(3)+5:2(7)-[3,3(7):0,(304)-1/3-10]} Help me

Answer 1

6/15:{3,25:26*1(3)+5:2(7)-[3,3(7):0,(304)-1/3-10]}=
=2/5:{325/100:26*(13-1)/9+5:(27-2)/9-[(337-33)/90:304/999-1/3-10]}=
=2/5:[325/100:26*12/9+5:25/9-(304/90:304/999-1/3-10)]=
=2/5:[325/2600*4/3+9/5-(111/10-1/3-10)]=
=2/5:[1300/2600*1/3+9/5-(333/30-10/30-300/30)]=
=2/5:(1/6+9/5-23/30)=
=2/5:(5/30+54/30-23/30)=
=2/5:36/30=
=2/5*30/36=
=6/18=
=1/3

Answer 2

3,25=3 intregi 25/100= 3 intregi 1/4= 13/4

1,(3)=1 intreg 3/9= 1 intreg 1/3= 4/3

2,(7)=2 intregi 7/9= 25/9

3,3(7)=3 intregi (37-3)/90=3 intregi 34/90 =3 intregi 17/45= 152/45

0,(304)=304/999

6/15 :{ 13/4 : 26 * 4/3  + 5: 25/9 -[152/45 : 304/999-1/3-10]}

6/15 :[ 13/4 * 1/26 * 4/3 + 5 * 9/25 -( 152/45 * 999/304 -1/3 -10)]

6/15: [ 1/1 * 1/2 * 1/3 + 9/5 -( 1/5 * 111/2 -1/3 -10)]

6/15 : [ 1/6 +9/5- (111/10 -1/3 -10)]    aducem la acelasi numitor in (...)

6/15 : [ 1/6 + 9/5 - (333-10-300)/30]

6/15 :(1/6 +9/5 - 23/30) aducem la acelasi numitor in (...)

2/5 : (5+54-23)/30

2/5 : (59-23)/30

2/5 : 36/30

2/5 * 30/36= 6/18= 1/3
