Determina valoarea de adevar:
a) 81: 3 + 2 504 = 93 : 3 + 2 500
72:3+ 4 837 = 68: 2 + 4 259
96 : 6 + 1 902 = 48: 3 + 1 865
(282 + 318): 10
b) (341 + 259): 10
(137+ 138): 25 = (973 - 852): 11
(428 + 472) : 30 = (124 + 476): 20​

Răspuns :

81 : 3 + 2504 = 93 : 3 + 2500

27 + 2504 = 31 + 2500

2531 = 2531 (A)

72 : 3 + 4837 = 68 : 2 + 4259

24 + 4837 = 34 + 4259

4861 = 4293 (F)

96 : 6 + 1 902 = 48 : 3 + 1 865

16 + 1902 = 16 + 1865 (F)

(282 + 318): 10  = (341 + 259): 10

600 : 10 = 600 : 10 (A)

(137+ 138) : 25 = (973 - 852) : 11

275 : 25 = 121 : 11

11 = 11 (A)

(428 + 472) : 30 = (124 + 476) : 20​

900 : 30 = 600 : 20

30 = 30 (A)
