trung bình 2 xe chở số tấn hàng là
(5 tấn 680 kg + 4 tấn 580 kg):2=5 tấn 130 kg
đổi : 5 tấn 680 kg =5680 kg
4 tấn 580 kg = 4580 kg
trung bình cộng 1 xe là:
(5680+4580):2 =5130 ( kg gạo)
10 xe có số bao gạo là:
120.10=1200(bao)
Đội xe vận tải chuyển về kho tất cả số tấn gạo là:
1200.100=120000(kg)
120000kg=120 tấn
Đáp số:120 tấn gạo.
Số kg xe tải bé chở được:
50x16=800(kg)
Đổi 800 kg=8 tạ
Xe tải lớn chở được:
70x90=6300(kg)
Đổi 6300 kg=63 tạ
Xe tải lớn chở được nhiều hơn xe tải bé số tạ gạo là:
64-8=55(tạ)
Đáp số: 55 tạ
Cả hai kho chứa số tấn gạo là:
12 tấn 753 kg + 8 tấn 247 kg
= 20 tấn 1000 kg = 21 tấn.
Ta có: 21 : 6 = 3 (xe) dư 3 tấn.
Ta thấy 3 tấn dư này cũng cần thêm một xe để chở.
Vậy số xe cần ít nhất là:
3 + 1 = 4 (xe)
Đáp số: 4 xe.
Đổi: 125 tấn = 1250 tạ
Số gạo đã chở là:
72 x 11 = 792 (tạ)
Số gạo còn phải chở là:
1250 - 792 = 458 (tạ)
Đ/S: 458 tạ
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 được số tấn gạo là:
3600 : 1000 = 3,6 tấn
4 m3 72 dm3 = 4,072 m
5 dam3 46m2 = 5046 m2
27% của 150 kg là: 40,5 kg
