Tổng số kg gạo nếp và gạo tẻ trong kho là:

                                                                   55x(125+75)= 11000(kg)

                                                             Lượng gạo còn lại trong kho là:

                                                                  11000:4=2750(kg)

                                                          Số kg gạo nếp và gạo tẻ đã chuyển đi là:

                                                                11000 - 2750= 8250(kg)

                                                                             Đáp số: 8250kg

Khối lượng của 30 bao gạo tẻ là:

30 x 40 = 1200 ( kg )

Khối lượng của 40 bao gạo nếp là:

40 x 20 = 800 ( kg )

Đổi : 1200 kg = 1,2 tấn

         800 kg = 0,8 tấn

Xe đó chở được số tấn gạo là:

1,2 + 0,8 = 2 ( tấn )

               Đáp số : 2 tấn gạo

Xe đó chở số tấn gạo là:

(30×40)+(40×20)=2000(kg)=2(tấn)

                              Đáp số: 2 tấn

2000  kg  k nhaaa cam on nhieu

20 bao gạo tẻ cân nặng là

50x20=1000 kg

40 bao gạo nếp cân nặng là

25x40=1000 kg

xe đó chở số tấn là

1000+1000=2000 kg

đáp số : 2000 kg

chúc bạn học giỏi hơn 

tk mình nha

xe đó chở bao gaọ  tẻ hết số tấn là:50 * 20=1000(kg)=1 tấn

xe đó chở số tấn gạo nếp là:25*40=1000(kg)=1 tấn

 xe đó chở tất cả số tấn gạo là:1+1=2(tấn)

                                              Đáp số:2 tấn

Số kg gạo tẻ là:

30.40=1200 (kg)

Số gạo  nếp là:

40.20=800 (kg)

Xe chở số tấn gạo là:

800+1200=2000(kg)

2000 kg=2 tấn

Đáp số : 2 tấn

đổi 40 tấn = 40000kg

vì số bao gạo tẻ bằng số bao gạo nếp nên gọi số bao gạo mỗi loại là x (bao)

số kg gạo tẻ là: 50x (kg)
số kg gạo nếp là: 30x (kg)
vì có tổng là 40 tấn gạo và tẻ nên ta có: 50x + 30x = 40000 => x= 500 (bao)
số gạo tẻ: 50 x 500 = 25000 kg = 25 tấn
số gạo nếp: 30 x 500 = 15000 kg = 15 tấn
BÀI NÀY CŨNG DỄ THÔI, CHỈ CẦN SUY NGHĨ 1 CHÚT :)) CỐ LÊN BÉ

Gọi số bao gạo mỗi loại là a

Số gạo tẻ là 50xa

Số gạo nếp là 30xa

Đổi 40 tấn = 40.000 kg

50xa + 30xa  = 40.000

80a = 40.000

a = 500

Số gạo tẻ là: 50 xa = 50 x500 = 25.000 kg = 25 tấn

Số gạo nếp là 30xa = 30 x 500 = 15.000 kg = 15 tấn

135 tấn = 135000 kg 

số bao là 

135000 :(50+40)= 1500 ( bao)

mỗi kho có số bao là

1500:2= 750(bao)

kho 1 có 750 x 50= 37500(kg)

kho 2 có 750 x 40= 30000(kg)

                              đổi 37500 kg =75/2 tấn 

                                     30000kg = 30 tấn 

                                         đáp số...

  tick cho tui nhó

khối lượng của xe đó là 2600kg nha 

nhớ nhé

20 bao gao nep can nang so kg la:

  20x45=900(kg)

20 bao gao te can nang so kg la:

   20x40=800(kg)

Xe do can nang so kg la:

  900+800=1700(kg)

                D/S:1700 kg

 Xe đó chở được tất cả :

   ( 45 . 20 ) + ( 40 . 40 ) = 2500 ( kg )

Nếu bạn không làm gộp bạn có thể tách ra làm 3 lời giải 

140 bao gạo tẻ nặng số ki - lô - gam là :

10 x 140 = 1400 ( kg )

120 bao gạo nếp nặng số ki - lô - gam là:

5 x 120 = 600 ( kg )

Có tất cả số tấn gạo là :

1400 + 600 = 2000 ( kg )

Đổi 2000 kg = 2 tấn

Đáp số: 2 tấn gạo

140 bao gạo tẻ nặng số ki - lô - gam là :

10 x 140 = 1400 ( kg )

120 bao gạo nếp nặng số ki - lô - gam là:

5 x 120 = 600 ( kg )

Có tất cả số tấn gạo là :

1400 + 600 = 2000 ( kg )

Đổi 2000 kg = 2 tấn

Đáp số: 2 tấn gạo

gạo tẻ nặng 

140x10=1400(kg)

gạo nếp nặng

120x5=600(kg)

cả hai nặng

1400+600=2000(kg)

2000kg=2 tấn
