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 \(30\times40+40\times20=1200+800=2000\left(kg.gạo\right)=2\left(tấn.gạo\right)\)

Cân nặng của 30 bao gạo tẻ:

\(30\times40=1200\left(kg\right)\)

Cân nặng của 40 bao gạo nếp:

\(40\times20=800\left(kg\right)\)

Số gạo xe đó chở:

\(1200+800=2000\left(kg\right)=2\left(tấn\right)\)

Số gạo tẻ cân nặng :

30 x 40 = 1200 ( kg )

Số gạo nếp cân nặng  :

40 x 20 = 800 ( kg )

Xe độ cho hàng nặng :

1200 + 800 = 2000 ( kg ) = 2 tấn

                  Đáp số : 2 tấn

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

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

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

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

khối lượng của xe đó là 2600kg nha 

nhớ nhé

20 bao gao nep can nang so kg la:

  20x45=900(kg)

20 bao gao te can nang so kg la:

   20x40=800(kg)

Xe do can nang so kg la:

  900+800=1700(kg)

                D/S:1700 kg

 Xe đó chở được tất cả :

   ( 45 . 20 ) + ( 40 . 40 ) = 2500 ( kg )

Nếu bạn không làm gộp bạn có thể tách ra làm 3 lời giải 

a) 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

b) Đổi 13km500m = 13500m

Hiệu số phần bằng nhau là 5 - 2 = 3 (phần)

Độ dài đoạn đường AC là 13500 : 3 x 2 = 9000 (m)

Độ dài đoạn đường CB là 13500 + 9000 = 22500 (m)

Độ dài đoạn đường AB là 9000 + 22500 = 31500 (m)

a) 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

b) Đổi 13km500m = 13500m

Hiệu số phần bằng nhau là 5 - 2 = 3 (phần)

Độ dài đoạn đường AC là 13500 : 3 x 2 = 9000 (m)

Độ dài đoạn đường CB là 13500 + 9000 = 22500 (m)

Độ dài đoạn đường AB là 9000 + 22500 = 31500 (m)
