Answer 2

Află numerele necunoscute:
495:a=5
a= 495:5
a=99
495:99=5

(27×41):b=9
1107:b=9
b=1107:9
b=123
(27x41):123=9

(321-12×12+6(:c=3
(321-144+6):c=3
(177+6):c=3
183:c=3
c=183:3
c=61
(321-12x12+6):61=3

d:(726:3)=6
d:242=6
d=6x242
d=1452
1452:(726:3)=6

x:8=115rest6
x=115x8+6
x=920+6
x=926
926:8=115 rest 6

y:(81:9)=155rest4
y:9=155 rest 4
y=155x9+4
y=1395+4
y=1399
1399:(81:9)= 155 rest 4

623:z=5rest 3
z= (623-3):5
z=620:5
z=124
623:124=5 rest 3

962:w=3rest2
w= (962-2):3
w=960:3
w=320
962:320=3 rest 2
