 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
