Question

calculati:

28/31*[1/4+(2 intregi si 1/2 - 7/4) : 7/8]=


( vreau rezolvarea nu raspunsul

Answer 1

28/31•[1/4+(2intregi si 1/2-7/4):7/8]=

=28/31•[1/4+(5/2-7/4):7/8]=

~la 5/2 amplificam cu 2

=28/31•[1/4+(10/4-7/4):7/8]=

=28/31•(1/4+3/4:7/8)=

=28/31•(1/4+3/4•8/7)=

~8 se simplifica cu 4 deci rezulta ca 3/4•8/7=3/1•2/7

=28/31•(1/4+3/1•2/7)=

=28/31•(1/4+6/7)=

~1/4 se amplifica cu 7 si 6/7 se amplifica cu 4

=28/31•(7/28+24/28)=

=28/31•31/28=

~28 se simplifica cu 28 iar 31 se simplifica cu 31 deci ramane 1/1
