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
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.

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

Khối lượng của gạo tẻ :
30 x 40 = 1200 ( kg )
Khối lượng cụa gạo nếp :
40 x 20 = 800 ( kg )
Khối lượng mà xe đó chở :
1200 + 800 = 2000 ( kg )
2000 kg = 2 tấn
Đáp số : 2 tấn
28 tháng 10 2019
số kg gạo tẻ tất cả là
40 x 30 = 1200 kg
số kg gạo nếu là
40 x 20 = 800 kg
có tất cả số kg là
1200 + 800 = 2000 kg
đổi 2000 kg = 2 tấn,
có tất cả 2 tấn gạo
31 tháng 1 2016
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

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). số kg gạo tẻ là: 30 x 40= 1200kg
số kg gạo nếp là: 40 x 20 = 800kg
tổng số tấn gạo xe đó chở là: 1200+800= 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
Xe đó chở \(30\times40+40\times20=1200+800=2000\left(kg.gạo\right)=2\left(tấn.gạo\right)\)
