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

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.

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=2000kg

tự tóm tắt nhé:

ngày thứ hai bán đc số kg đường là:

800x4/5=...........(kg)

ngày thứ 3 bấn đc số kg đường là:

2000-800-.....=........

đ/s

xin lỗi vì mk ko tính ra cho bn nhé

Ngay 2 bán là:                                            2 tấn =2000kg

     800:5= 160 kg đường

Ngay3 bán là:

     2000-800-160=1040 kg đường

             Đáp số:     1040kg đường

16 Người làm xong một công việc trong 3 ngày. Hỏi 8 người thì làm xong công việc đó trong bao nhiêu ngày? 

Giải ngay hộ tớ ngay bây giờ nha  

Cảm ơn bạn 😍😍😍😄😄😄

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  

số kg đường ngày thứ hai bán được là

300*2=600 (kg )

số kg đường ngày thứ 3 bán được là

1000 - (300+600) = 100( kg)

Bài giải

Ngày thứ hai cửa hàng bán được số kg đường là: 750 : 2 = 375 kg

Trung bình mỗi ngày cửa hàng đó bán được  số ki-lô-gam đường là:

(750+375+630) : 3 = 585 kg

Đáp số: 585 kg

Giải:

2 tấn = 2000kg

Ngày thứ hai cửa hàng bán được số đường là :

400 x \(\frac{3}{5}\) = 240 (kg)

Cả hai ngày cửa hàng bán được số đường là :

400 + 240 = 640 (kg)

Cửa hàng còn lại số đường là :

2000 - 640 = 1360 (kg)

Đáp số: 1360 kg đường

Đổi 2 tấn = 2000 kg
 Ngày thứ 2 bán được số kg đường là :
400 : 5 x 3 = 240 (kg đường)
 Cửa hàng còn lại số kg đường là :
2000 - ( 400 + 240 ) = 1360 (kg đường)
Đáp số : 1360 kg đường

Số gạo ngày 2 bán được là

\(400.\frac{3}{5}=240\left(kg\right)\)

Đổi 2 tấn =2000kg

Sô dường cửa hạng còn lại

\(2000-\left(240+400\right)=1360\left(kg\right)\)

Vậy sô dường cửa hạng còn lại là 1360 kg
