Dau corona! ​

Answer 1

Răspuns:

a) 8×a=2008

a=2008:8

a=251

b) b:7=824

b=824:7

b=118 rest 1

c) c×6=4698

c=4698:6

c=783

d) 642:d=6

d=642×6

d=3.852

e) 891:e=9

e=891×9

e=8019

f) f:3=978

f=978×3

f=2934

g) gx5=1245

g=1245:5

g=249

h) 8xh=416

h=416:8

h=52

i) 1:9=649 rest 5

1×9+654

9+654=663

j) 4642:j=8 rest 2

j=4642:10

j=464 rest 2

k) 2822:k=9 rest 5

k=2822:14

k=201 rest 8

l) 1:5=643 rest 2

1×5+645

5+645=650
