Question

Alguem pode me ajudar nesses calculos

Answer 1

Resposta:

g) 1.098

2x9 = 18

20 x 9 = 180

100 x 9 = 900

900 + 180 + 18 = 1.098

h) 8.720

0 x 8 = 0

90 x 8 = 720

0 x 8 = 0

1.000 x 8 = 8.000

8.000 + 0 + 720 + 0 = 8.720

i) 11.725

5 x 5 = 25

40 x 5 = 200

300 x 5 = 1.500

2.000 x 5 = 10.000

10.000 + 1.500 + 200 + 25 = 11.725

j) 26

13 + 3 - 6 + (23 - 3 + 2) =

23 - 3 = 20 + 2 = 22

13 + 3 - 6 + 22

13 - 3 = 10

10 - 6 + 22

10 - 6 = 4

4 + 22 = 26

k) 140

200 - 100 + 50 - 10

200 - 100 = 100

100 + 50 = 150 - 10 = 140

l) 8

35 - 33 + (56 - 50) =

56 - 50 = 6

35 - 33 + 6 =

35 - 33 = 2 + 6 = 8

Answer 2

G)122×9=1,098

H)1090×8=8,720

I)2345×5=11,725

J)13+3-6+(23-3+2)=32

K)200-100+50-10=140

L)35-33+(56-50)=8

1090

×8=

8,720

122

2345

×5=

11,725

13+3-6+(23-3+2)

16-6+(20+2)

10+22=32

200-100+50-10

100+50-10

150-10=140

35-33+(56-50)

2+6=8
