Află numărul necunoscut a×5=35 5×a=40 a÷5=8 45÷a=5 a×4=36 a÷4=7 7×a=21 a÷3=8

Răspuns :

a x 5 = 35
a = 35 : 5
a = 7
7 x 5 = 35


5 x a = 40
a = 40 : 5
a = 8
5 x 8 = 40


a : 5 = 8
a = 8 x 5
a = 40
40 : 5 = 8

45 : a = 5
a = 45 : 5
a = 9
45 : 9 = 5


a x 4 = 36
a = 36 : 4
a = 9
9 x 4 = 36


a : 4 = 7
a = 7 x 4
a = 28
28 : 4 = 7


7 x a = 21
a = 21 : 7
a = 3
7 x 3 = 21


a : 3 = 8
a = 8 x 3
a = 24
24 : 3 = 8 .
