Explicație pas cu pas:
1,(5)= 15-1/9=14/9
16 intregi si 2/5= 16 ori 5+2/5=82/5
2 intregi si 3/5= 2 ori 5+3/5= 13/5
Acum exercitiul este
14/9 :2/3- {82/5 -[ 14+ ( 3/8 + 5/8 x 13/5)]}=
= 14/9 x 3/2 - { 82/5 - [ 14 + ( 3/8 + 13/8)]}=
= 7/3- [ 82/5 - (14+ 16/8)]=
= 7/3 - [ 82/5 -( 14 +2)]=
= 7/3 - ( 82/5- 16)=
= 7/3 - ( 82/5 - 16 ori 5/5)=
= 7/3 - ( 82/5 -80/5)=
= 7/3 - 2/5=
= 7 ori 5/15 - 2 ori 3/15=
= 35/15 - 6/15=
=29/15
