Đổi 2 tấn = 2000 kg
Ngày thứ hai bán được số kg đường là
\(800\cdot\frac{4}{5}=640\)( kg)
Ngày thứ 3 bán được số kg đường là
\(2000-800-640=560\)( kg)
2 tấn = 2000 kg
ngày thứ 2 bán được :
800 x 4/5 = 640 (kg)
ngày thứ 3 bán được :
2000 - 800 - 640 = 560 (kg)
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)

xin lỗi vì mk ko tính ra cho bn nhé
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 )

số phần trăm hai ngày bán được là:
35% + 40% = 75%
số phần trăm ngày thứ ba bán được là:
100% - 75% = 25%
ngày thứ ba bán được là:
2400 : 100 x 25 = 600 (kg)
đáp số: 600 kg
so phan tram ban duoc 2 ngay dau la :
100-(35%+45%)=25%
so phan tram ban ngay thu 3 la :
100%-25%=75%
ngay thu 3 ban so kg la :
2400:100*75=600(kg)
d/s:600 kg
Ngày thứ nhất bán được số đường là:
2400:100x35 = 840 (kg)
Ngày thứ hai bán được số đường là :
2400:100x40 = 960 (kg)
Cả hai ngày bán được số đường là :
840+960 = 1800 ( kg )
Ngày thứ ba bán được số đường là:
2400-1800= 600 ( kg )
Đáp số: 600 ki-lô-gam đường
Số đường ngày thứ nhất bán là
2400.35%=840kg
so đường ngày 2 bán là
2400.40%=960kg
Số kg đường ngày 3 bán là
2400- 960 -840= 600kg
đáp số 600 kg
Đổi: 2 tấn = 2000 kg
Số kg đường ngày hai bán được:
\(800\times\dfrac{4}{5}=640\left(kg\right)\)
Số kg đường ngày 3 bán được:
\(2000-800-640=560\left(kg\right)\)
Ngày thứ ba bán được:
\(2000-800-800\cdot\dfrac{4}{5}=560\left(kg\right)\)
