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:

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 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
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.
Xe đó chở số gạo là:
( 50 x 25 ) + ( 30 x 25 ) = 2000 ( kg ) = 2 tấn
Đáp số : 2 tấn
Xe đó chở số gạo là :
50 x 25 + 30 x 25 = 2000 kg = 2 tấn
Đ/s :2 tấn
Bài làm
20 bao gạo tẻ nặng số kg là
50x20=1000 ( kg )
40 bao gạo nếp nặng số kg là
40x25=1000 ( kg )
Xe đó chở tất cả số gạo là
1000+1000=2000 ( kg )
Đổi 2000 kg =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
Xe đó chở số kg gạo tẻ là:
45 x 15 = 675 ( kg )
Xe đó chở số kg gạo nếp là:
32 x 12 = 384 ( kg )
Xe đó chở tất cả số kg gạo là:\
675 + 384 = 1059 ( kg )
đs : 1059 Kg gạo Mong lời giải của mình giúp ích cho bạn ^^
