a) 65 : 5 + ( 24 : 12 + 5 ) = ?
b) 90 : 6 + 2 x ( 25 : 25 + 14 ) = ?
c) 8 x 12 : 3 + [ 2 + ( 4 x 3 - 2 x 3)] = ?
Repede , va rog . Dau coroana .


Răspuns :

a. 13 + 7 = 20
b. 15 + 30 = 45
c. 32 + (2+ 6) = 40
a) 65 : 5+(24:12+5)=
=13+(2+5)
=13+7
=20

b) 90:6+2×(25:25+14)=
=15+2×(1+14)
=17×15
=255

c) 8×12:3+[2+(4×3-2×3)]=
=8×4+[2+(12-6)]
=32+(2+6)
=32+8
=40

SPER CĂ TEAM AJUTAT!!!
