Question

Verifică egalitățile. Notează cu A (adevărat) sau F (fals). 2x5=4x6-28:7 a) 6+25:5-1+ b) 100-90:9+80:8-10 × 1 = 4 x 10+ 2 × 3 ×5+2×2×5 +3x3x3-9x1 ​

Answer 1

a. 2 × 5 = 10

4 x 6 - 28 : 7 = 24 - 4 = 20 FALS

b. 100 - 90 : 9 + 80 : 8 - 10 × 1 = 100 - 10 + 10 - 10 = 90

4 × 10 + 2 × 3 × 5 + 2 × 2 × 5 + 3 × 3 × 3 - 9 × 1

= 40 + 30 + 20 + 27 - 9 = 90 + 27 - 9 = 108 FALS

Answer 2

a)

2×5=4×6-28:7 F

10=20

6+25:5-1=

25:5=

5+6=

11-1=

10

b)

100-90:9+80:8-10×1=4×10+2×3×5+2×2×5= F

90=108

100-90:9+80:8-10×1=

100-10+10-10=

90+0=

90

4×10+2×3×5+2×2×5+3×3×3-9×1

40+6×5+4×5+9×3-9=

40+30+20+27-9=

70+47-9=

70+38=

108
