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:

\(2000-800-800\cdot\dfrac{4}{5}=560\left(kg\right)\)

Ngày thứ ba bán được:

\(2000-800-800\cdot\dfrac{4}{5}=560\left(kg\right)\)

bán được là 640 kg đường

k nha mik k lại

ĐỔI 2 tấn = 2000 kg

Ngày thứ 2 cửa hàng bán được số ki lô gam đường là  

            400 * 3/5 = 240 <kg>

Cửa hàng đã bán được số ki lô gam đường là

        2000 - <400+240> = 1360 <kg>

xin lỗi nha mk làm sai 

   cửa hàng bán đc là  400 +240 =640 nha

2 tấn = 2000 kg

Số kg đường ngày thứ hai cửa hàng bán được là :

400 x 3/5 = 240 ( kg)

Số kg ngày thứ nhất và ngày thứ hai cửa hàng bán được là :

400 + 240 = 640 ( kg)

Số kg đường còn lại sau khi bán trong hai ngày là :

2000 - 640 = 1360 ( kg)

         Đs : 1360 kg đường

Một cửa hàng trong ba ngày bán được có 3 tấn đường ngày đầu bán được 800 kg ngày Thứ Hai bán được số đường bằng 4/5 số đường bán được trong ngày đầu hỏi ngày thứ ba bán được bao nhiêu kilôgam

CỬA HÀNG CÓ 2 TẤN ĐƯỜNG . NGÀY ĐẦU HỌ BÁN ĐƯỢC 400 KG . NGÀY THỨ HAI HỌ BÁN ĐƯỢC BẰNG 1 VÀ 3/5 NGÀY ĐẦU . HỎI CỬA HÀNG CÒN LẠI BAO NHIÊU KG ĐƯỜNG

tớ trả lời rùi đấy

tk nha

Ngày thứ 2 bán được số kg gạo là :

400 : 5 x 3 = 240 ( kg )

Đổi : 2 tấn = 2000 kg

=> Tổng ngày đầu và ngày 2 bán được số kg gạo là :

400 + 240 = 640 ( kg )

=> Số đường còn lại là :

2000 - 640 = 1360 ( kg )

Đ/S : 1360 kg

2 tấn = 2000 kg

Ngày thứ 2 bán được:

400.3/5=240 kg

số đường còn lại là :

2000-(400+240)=1360 kg

                      Đáp số: 1360kg

Ngày thứ ba bán được:

1500-350-700=450(kg)

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)

\(1,5\) tấn = \(1500kg\)

Ngày thứ hai bán được số đường là :

            \(350\)x\(2=700\left(kg\right)\)

Hai ngày đầu bán được số đường là :

             \(350+700=1050\left(kg\right)\)

Ngày thứ ba bán được số đường là : 

            \(1500-1050=450\left(kg\right)\)

                 Đ/S:\(450kgđường\)

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)

Đổi 2 tấn =2000 kg

Ngày thứ hai bán được số kg đường là:

800 X 4/5=640(kg đường)

Vậy ngày thứ ba bán được số kg đường là:

2000-(800+640)=560(kg đường)

                     Đ/S:560 kg đường

giải

số đường ngày thứ 2 bán đc là:

300 x 2 = 600 (kg)

số đường ngày thứ 1 và ngày thứ 2 bán đc là:

300+600= 900 (kg)

Ngày thứ ba bán đc bn tấn đường là:

1 tấn = 1000kg

1000-900= 100 (kg)

đáp số : ngày 2 = 300(kg)

ngày 3 = 100(kg)

1 tấn = 1000 kg

ngày thứ ba bán được số kg đường là 

1000 - 300 - ( 300 x 2 ) = 100 ( kg )
