Question

5 x 6 : 3 + 27 :9 x 3 +8 =
493 + 18 : 9 x 4 - ( 200- 9 x 9 ) =
2+ ( 3x 4 : 6 x 50 -50 ) + ( 50 : 10 x 6 : 3 + 20 ) =
600 – 48 + 48 : 8 x 9 – 50 : 5 : 10 x 3 =
(90 – 6 x 7) : 8 + (21 + 21 : 3) =​

Answer 1

Răspuns:

a) 10+9+8=27

b) 493+8-119=382

Explicație pas cu pas:

c) 2+50+30=82

d) 600-48+54-3=603

e) (90-42) :8+(21+7)= 48:8+28=6+28=34

Answer 2

1). 5×6:3+27:9×3+8=

30:3+3×3+8=

10+9+8=19+8=27

2). 493+18:9×4-(200-9×9)=

493+2×4-(200-81)=

493+8-119=

501-119=382

3). 2+(3×4:6×50-50)+(50:10×6:3+20)=

2+(12:6×50-50)+(5×6:3+20)=

2+(2×50-50)+(30:3+20)=

2+(100-50)+(10+20)=

2+50+30=

52+30=82

4). 600-48+48:8×9-50:5:10×3=

600-48+6×9-10:10×3=

600-48+54-1×3=

552+54-3=

606-3=603

5). ( 90-6×7 ) : 8 + ( 21 + 21 : 3 ) =

( 90-42 ) :8 + ( 21 + 7 ) =

48 : 8 + 28 =

6+28=34
