Số lớn chia số bé = 4(dư 19)

=> Số lớn = số bé x 4 + 19

Theo đề bài, ta có:

Số lớn - số bé = 133

=> Số bé x 4 + 19 - số bé = 133

Bớt cả 2 vế đi 19 đơn vị, ta được:

số bé x 4 - số bé = 114

=> số bé x 3 = 114

=> số bé = 38

=> số lớn là: 38 + 133 = 171

hiệu 2 số là: 133-19= 114

số bé là: 114:(4-1)= 38

đ/s:...

k mk nhé

thanks

số lớn là 81 

số bé là 38

Thương là 4 thì số bị chia gấp 4 lần số chia.

Hiệu 2 số mà không dư: 133 - 19 = 114

Số bé: 114 : ( 4-1) x 1 = 38

Số lớn: 4 x 38 + 19 = 171

Đây là bài toán có dạng hiệu - tỉ . "Số lớn chia cho số bé được 4 và dư 19", có nghĩa là số lớn trừ đi 19 sẽ gấp 4 lần số bé . Hiệu là 133 có nghĩa là số lớn hơn số bé 133 đơn vị. Em vẽ sơ đồ và đưa về dạng hiệu-tỉ là giải rất đơn giản. 

Số bé: |-----------| 

Số lớn:|-----------|------------|----------... dư 19) 

Hiệu ( 3phần và 19) ----------------133----------------- 

Khi số lớn gấp 4 lần số bé thì hiệu của hai số là: 

133 - 19 = 144 

Khi đó,hiệu số phần bằng nhau là: 

4 - 1 = 3 

Số bé là: 

114 : 3 = 38 

Số lớn :

133 + 38 = 171

hiệu mới là:133-19=114

bản tự vẽ sơ đồ nha

số lớn là:114:(4-1)x4+19=171

đáp số:171

Hiệu số phần :

4 dư 19 - 1 = 3 dư 19

Số bé : 

(133 - 19) : 3 = 38

Số lớn :

38  x 4 + 19 = 171

Bé : 58

 Lớn :128 

Nhớ k cho mình nha

Số bé là

   (186-12) : (2+1) = 58

Số lớn là

    186-58=128 nhé

Số bé là :

 \(\left(186-12\right):\left(2+1\right)=58\)

Số lớn là :

 \(186-58=128\)
