xe đó chở được số kg gạo là:
18*50+15*20 = 1200 (kg)
đổi: 1200 kg = 12 tạ
đáp số: 12 tạ 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

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
20 bao gạo tẻ nặng : 20 x 50 = 1000(kg)
40 bao gạo nếp nặng : 25 x 40 = 1000(kg)
Xe đó chở tất cả số kg gạo là : 1000 + 1000 = 2000(kg)
Đổi : 2000 kg = 2 tấn
Xe đó chở \(50\times20+25\times40=2000\left(kg\right)=2\left(tấn\right)\)
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.
Số kg gạo tẻ:
50 x 25 = 1250 (kg)
Số kg gạo nếp:
30 x 25 = 750 (kg)
Tổng số kg:
1250 + 750 = 2000 (kg)
Đổi 2000kg = 2 tấn
Đs:..
25 bao gạo tẻ nặng :
50 x 25 = 1250 ( kg )
25 bao gạo nếp cân nặng :
30 x 25 = 750 ( kg )
Xe đó chở tất cả :
1250 + 750 = 2000 ( kg ) = 2 tấn
SỐ KI LÔ GAM GẠO TẺ LÀ: 25 X 50 = 1250KG
SỐ KI LÔ FAM GẠO NẾP LÀ: 25 X 30 =750KG
XE ĐÓ CHỞ SỐ TẤN GẠO LÀ: 1250 + 750 = 2000KG = 2 TẤN
ĐÁP SỐ: 2 TẤN
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 số kg gạo là:
(50x18)+20x15=1200(kg)
Đổi :1200kg=12 tấn
Đáp số:12 tấn
12 tấn nha bạn chúc bạn học giỏi
