Ta có: Số lớn gấp 10 lần số bé và cộng thêm R (R là chữ số hàng đơn vị)

(1644-R):11=149(dư 5)

Vậy số lớn là:

149x10+5=1495

Đ/s: 1495

Dễ hiểu hơn : Ta có a là số lớn

, b là số nhỏ

còn d là chữ số hàng đơn vị của số lớn

Theo đề : a : 10 + d = b do đó 10b + d = a

thay vào : a + b = 10b + d + b = 11b +d= 1644 

mà 1644= 11 . 149 + 5 suy ta a = 149 .10 +5 = 1495

kết quả là 1945

1945 la sai

1495 lafchinhs xác nhất

kết quả là 1495

vi sao lại chia 11

Gọi số lớn là abcd, suy ra số bé là abc
Theo bài ra, ta có: abcd + abc = 1644
Ta có thể đặt tính như sau:
Từ hàng đơn vị: d + c < 20, do đó nhớ < 2
Từ hàng chục: c + b < 20, do đó nhớ < 2
Từ hàng trăm: b + a < 20, do đó nhớ < 2
Từ hàng nghìn ta có: a + 0 = 1, vậy a = 1
Xét hàng trăm ta có: b + 1 + 1 (nhớ) = 6, vậy b = 4
Xét hàng chục ta có: c + 4 + 1 (nhớ) = 4, vậy c = 9
Xét hàng đơn vị ta có: d + 9 = 4, vậy d = 5
Số lớn là: 1495
