Trả lời:

Đổi đơn vị:

600Kg= \(\frac{3}{5}\)Tấn

=> Xe tải nặng: 2-\(\frac{3}{5}\)=\(\frac{7}{5}\)=(1\(\frac{2}{5}\))tấn (Chọn C)

1.Đổi 600 kg = \(\frac{3}{5}\)tấn .

  Vậy chiếc xe tải nặng số kg là :

                                                 2 - \(\frac{3}{5}\)=\(\frac{7}{5}\)(tấn)

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

                                               Bài giải 

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

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 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

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
