Đổi 300 kg = 0,3 tấn
Ngày thứ hai bán được số tấn là:
0,3 x 2 = 0,6 ( tấn )
Ngày thứ ba bán số tán là:
1 - 0,3 - 0,6 = 0,1 ( tấn )
Đổi 0,1 tấn = 100 kg
Đáp số: 100 kg
đổi 1 tấn =1000kg
ngày thứ 2 bán được số kg đường là:
300*2=600{kg}
ngày thứ 3 bán được số kg đường là:
1000-{600+300}=100{kg}
đáp số:100 kg đường
1 tấn = 1000 kg
Ngày thứ hai bán được : 300 x 2 = 600 (kg)
Hai ngày đầu bán được : 300 + 600 = 900 (kg)
Ngày thứ ba bán được : 1000 - 900 = 100 (kg)
Đáp số: 100kg đường.
1 tấn = 1000 kg
Ngày thứ hai bán được : 300 x 2 = 600 (kg)
Hai ngày đầu bán được : 300 + 600 = 900 (kg)
Ngày thứ ba bán được : 1000 - 900 = 100 (kg)
Đáp số: 100kg đường.
Đổi 1,5 tấn = 1500kg
Ngày thứ 2 cửa hàng bán được: 350x2 = 700(kg)
Ngày thứ 3 cửa hàng bán được: 1500-700-350=450(kg)
Ta có :1 tấn=1000kg
Ngày thứ 2 bán đc số đường là :300x2=600(kg)
=>Ngày thứ 3 bán đc số đường là:1000-300-600=100(kg)
Đáp số:100kg đường.
1 tấn = 1000 kg đường
Ngày thứ 2 bán được: 300 x 2 = 600 ( kg )
Ngày thứ 3 bán được: 1000 - 600 - 300 =100 (kg)
Đổi 1 tấn = 1000 kg
Ngày thứ hai cửa hàng bán được số đường là:
300 × 2 = 600 (kg)
Ngày thứ ba cửa hàng bán được số đường là:
