Giải ngay hộ tớ ngay bây giờ nha  

Cảm ơn bạn 😍😍😍😄😄😄

Ngày đầu bán được:

2 400 x 35% = 840 (kg đường)

Ngày thứ hai bán được:

2 400 x 40% = 960 (kg đường)

Ngày thứ ba bán được:

2 400 - (840+960) = 600(kg đường)

Đ.số: 600 ki-lô-gam đường

Hai bạn đều trả lời đúng nha

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

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:\(450kgđường\)

4 tấn = 4000 kg

Ngày thứ hai bán được là: 900 x \(\frac{4}{3}\)= 1200 (kg)

Ngày thứ ba bán được là: 4000 - 1200 - 900 = 1900 (kg)

                                                        Đáp số: 1900 kg

NGÀY 2 BÁN ĐƯỢC SỐ GẠO LÀ:

       900*4/3=1200[KG]

                  4 TẤN=4000 KG

NGÀY THỨ 3 BNS ĐƯỢC SỐ KG GẠO LÀ:

          4000-1200-900=1900[KG]

                           ĐÁP SỐ:1900 KG

Ngày thứ hai bán được số gạo là :

   900 . \(\frac{4}{3}\)= 1200 (kg)

Đổi : 4 tấn = 4000 kg

Ngày thứ ba bán được số gạo là :

   4000 - 900 - 1200 = 1900 (kg)

              Đ/s : 1900 kg gạo.

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

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

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 = 1000kg

Ngày thứ hai bán được là: 300x2=600 (kg)

Hai ngày đầu bán được là:300 + 600=900(kg)

Ngàu thứ ba bán được là: 1000-900=100(kg)

Đ/s:100kg đường
