Xe đó chở số ki lô gam gạo tẻ là : 30 x 40 = 1200 ( kg )

Xe đó chở số ki lô gam gạo nếp là : 20 x 40 = 800 ( kg )

Xe đó chở số tấn gạo là : 1200 + 800 = 2000 ( kg )

                                 Đổi : 2000 kg = 2 tấn 

                                                     Đáp số : 2 tấn 

Số gạo tẻ cân nặng là:

40 x 30 = 1200 (kg)

Số gạo nếp cân nặng là:

20 x 40 = 800 (kg)

Xe đó chở số kg gạo là:

1200 + 800 = 2000 (kg) 

Đổi 2000 kg = 2 tấn

                  Đáp số: 2 tấn

 30 bao gạo tẻ cân nặng 30 x 40 =1200 (kg)

40 bao gạo nếp cân nặng 40 x 20 = 800 (kg)

Khối lượng gạo xe đó chở là 1200 + 800 = 2000 (kg)

Đổi 2000kg = 2 tấn

Bài giải

Khối lượng gạo tẻ xe đó chở được là :

40 x 30 = 1200 kg gạo = 1,2 tấn gạo

Khối lượng gạo nếp xe đó chở được là :

20 x 40 = 800 kg gạo = 0,8 tấn gạo

Khối lượng gạo xe đó chở được tất cả là :

1,2 + 0,8 = 2 tấn gạo

Đáp số: 2 tấn gạo.

Xe đó chở số kg gạo tẻ là:

            30x40=1200 ( kg )

Xe đó chở số kg gạo nếp là:

            40x20=800 ( kg )

Vậy xe đó chở số kg gạo là:

            1200+800=2000 ( kg )

Đổi:        2000 kg = 2 tấn

          Đáp số: 2 tấn

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 gạo tẻ xe đó chở là:

   40 x 30 = 1200 (kg)

Số gạo nếp xe đó chở là:

   20 x 40 = 800 (kg)

Số gạo xe đó chở là:

   1200 + 800 = 2000 (kg)

                      Đ/S: 2000 kg

Số kg gạo nếp là: 

40 x 20 = 800 (kg)

Số kg gạo tẻ là :

30 x 40 = 1200 (kg)

Xe chở tổng số tấn gạo là: 

1200 + 800 = 2000 (kg) = 2 (tấn)

Xe đó chở:

\(30\cdot40+40\cdot20=2000\left(kg\right)\)

Đổi 2000kg=2 tấn

Hướng dẫn giải:

Số gạo tẻ xe chở được là :

25 x 50 = 1250 (kg)

Số gạo nếp xe chở được là :

30 x 25 = 750 (kg)

Tổng số gạo xe chở được là :

1250 + 750 = 2000 (kg)

Đổi 2000kg = 2 tấn

Đáp số : 2 tấn.

Tôi đéo biết

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

số kg gạo tẻ là

50.240=12000kg

số kg gạo nếp là

40.240=9600kg

TB 1 thuyền chở là

(*12000+9600):6=3600kg
