2000  kg  k nhaaa cam on nhieu

20 bao gạo tẻ cân nặng là

50x20=1000 kg

40 bao gạo nếp cân nặng là

25x40=1000 kg

xe đó chở số tấn là

1000+1000=2000 kg

đáp số : 2000 kg

chúc bạn học giỏi hơn 

tk mình nha

xe đó chở bao gaọ  tẻ hết số tấn là:50 * 20=1000(kg)=1 tấn

xe đó chở số tấn gạo nếp là:25*40=1000(kg)=1 tấn

 xe đó chở tất cả số tấn gạo là:1+1=2(tấn)

                                              Đáp số:2 tấn

Số kg gạo tẻ là:

50 x 32 = 1600 (kg)

Số kg gạo nếp là:

59 x 45 = 2655 (kg)

Vậy có tổng cộng:

1600 + 2655 = 4255(kg) = 4,255 tấn

ĐS: 4,255 tấn

Khối lượng của 30 bao gạo tẻ là:

30 x 40 = 1200 ( kg )

Khối lượng của 40 bao gạo nếp là:

40 x 20 = 800 ( kg )

Đổi : 1200 kg = 1,2 tấn

         800 kg = 0,8 tấn

Xe đó chở được số tấn gạo là:

1,2 + 0,8 = 2 ( tấn )

               Đáp số : 2 tấn gạo

Xe đó chở số tấn gạo là:

(30×40)+(40×20)=2000(kg)=2(tấn)

                              Đáp số: 2 tấn

16x30=...
số gạo tẻ là :

cửa hàng có số kg gạo là:
kết quả gạo tẻ+kết quả gạo nếp=....
bạn ghi kết quả nhé 
chúc bạn học tốt

Số kg gạo tẻ là:

30.40=1200 (kg)

Số gạo  nếp là:

40.20=800 (kg)

Xe chở số tấn gạo là:

800+1200=2000(kg)

2000 kg=2 tấn

Đáp số : 2 tấn

mỗi gói có số kg là:

250 : (10+15) = 10kg

15 túi gạo tẻ cân nặng

10 x 15 = 150kg

10 túi gạo nếp cân nặng

10 x 10 = 100kg

mỗi gói có số kg là:

250 : (10+15) = 10kg

15 túi gạo tẻ cân nặng

10 x 15 = 150kg

10 túi gạo nếp cân nặng

10 x 10 = 100kg

15 túi gạo tẻ cân nặng số ki-lô-gam là :

        250 / ( 10 + 5 ) * 15 = 150 ( kg )

10 túi gạo nếp cân nặng số ki-lô-gam là :

        250 - 150 = 100 ( kg )

100 kg gạo nếp ; 120 kg gạo tẻ

số bao gạo có tất cả: 
10+12=22 (bao) 
mỗi bao cân nặng: 
220:22=10 (kg) 
túi gạo nếp cân nặng: 
10x10=100(kg) 
túi gạo tẻ cân nặng: 
10x12=120 (kg)

k mk nha mn 

tổng số túi gạo là 10+12=22( túi gạo ). Do mỗi tui gạo đều cân nặng như nhau nên mỗi túi gạo sẽ cân nặng là 220:22=10(kg)

Số gạo nếp có là :10x10=100(kg)

Số gạo tẻ có là: 12x10=120(kg)

số gạo nếp là:220:[10+12].10=100[kg]

số gạo tẻ là:220-100=120 [kg]
