là 299

thaks bạn nha !!!!

trả lời đầy đủ cả bài giải nhé
 

Từ đề bài ta có được các đẳng thức sau

x=24.r₁+5

x=26.r₂+5

r₁-r₂=2=>r₁=r₂+2

thay vào biểu thức đầu ta được

x=24.(r₂+2)+5=24r₂+48+5=24r₂+53

=>2r₂-48=0

r₂=24

x=24.24+5=581

4 là số dư lớn nhất trong phép chia cho 5

Gọi số cần tìm là a và b = a + 16

b chia hết cho 5 và thương tăng thêm 4

b chia hết cho 9 và thương tăng thêm 2

Lúc này 2 thương hơn kém nhau 26 + 2 = 28

9 x 5 = 45 nên 45 chia cho 9 bằng 5 và 45 chia cho 5 bằng 9

Số b là : 45 x 28 : (9 - 5) = 315

Số cần tìm là : 315 - 16 = 299

299 la đúng đó chắc chắn 100% lun

Ban kia lam dung roi do

k tui nha

thanks

Gọi n là thương của phép chia cho 26, ta được:

26 x n + 5 = 24 x (n+2) + 5 = 24 x n + 48 + 5

2 x n = 48

n = 48 : 2 = 24

Số cần tìm là:

26 x 24 + 5 = 629

Đáp số:629
