Question

AJUTATI-MA VA ROG ESTE URGENT!!! DAU COROANA!!!

Answer 1

(328+97+100):(70+168x5:8)+20=525:(70+840:8)+20=525:(70+105)=525:175+20=3+20=23, raspunsul : numar impar
11/12,  22/22, 33/32, 44/42, 55/52, 66/62, 77/72, 88/82, 99/92
9/11+(3/11+5/11)=9/11+8/11=17/11,    23/19+(12/19+3/19)=23/19+15/19=38/19=2

Answer 2

1)
[ ( 328 + 97 + 100 ) : ( 70 + 168 × 5 : 8 ) ] + 20 = 23 
= [ 525 : ( 70 + 105 ) ] + 20 =
= ( 525 : 175 ) + 20 =
= 3 + 20 =
= 23 

Rezultatul calculului este 23,  un numar impar.

2) a)  x ≠ 0;   11 / 12 ;   22/ 22;   33/ 32;   44 / 42;   55/ 52;   66 / 62;  77 / 72;
88/82;   99 / 92 

b)   9 / 11 + ( 3 / 11 + 5 / 11) = 9 / 11 + 8 / 11 = 17 / 11 

     23 / 19 - ( 12 / 19 -  3 / 19 ) = 23 / 19 - 9 / 19 = 14 / 19
