k nha bạn

 Cảm ơn các bạn nhé

Chúc các bạn học giỏi

500 + 500 = 1 000

k mình nha

150 het

100 + 200 + 300 + 400 + 500

= (200 + 300 + 500) + 400 + 100

= 1000 + 400 + 100

= 1500

10 + 20 + 30 + 40 + 50

= 10 + 40 + (20 + 30 + 50)

= 50 + 100

= 150

200÷50=4

100÷20=5

300÷30=3

400÷10=40

500÷40=12.5

Nếu thấy đúng cấc nhe

200 :50 =4

100 : 20 =5

300:30=10

400:10=40

500:40= 12,5

ủng hộ nha

200 : 50 = 4

100 : 20 = 5

300 : 30 = 10

400 : 10 = 10

500 : 40 = 150
