Question

54. Află valorile lui .,a" din egalitățile: a) 32 : a = 4 a x 3 = 24 4 x 4 = 24 36:a = 4 b) (18 + 9): a = 3 (3 x 4): a = 2 a : (21 - 14) = 3 (72-56): a = 4​

Answer 1

Răspuns:

32:a=4=32:4=8

a×3=24=24:3=8

4×a=24=24:4=6

36:a=4=36:4=9

(18+9):a=3=27:a=3=27:3=9

a:(21-14)=2=a:7=2=2×7=14

(3×4):a=2=12:a=2=12:2=6

(72-56):a=4=16:a=4=16:4=4

Bafta!
