481abc:abc=1481
\(\Rightarrow\) (481000+abc)\(⋮\) abc=1481
\(\Rightarrow\) 481000:abc+1=1481\(\Rightarrow\) 481000\(⋮\) abc = 1480
Vậy abc =481000:abc=325 , do đó a=3, b=2,c=5
mik ko chắc chắn đâu
\(\overline{481abc}\div\overline{abc}=1481\)
\(\left(481000+\overline{abc}\right)\div\overline{abc}=1481\)
\(481000\div\overline{abc}+\overline{abc}\div\overline{abc}=1481\)
\(481000\div\overline{abc}+1=1481\)
\(481000\div\overline{abc}=1481-1\)
\(481000\div\overline{abc}=1480\)
\(\Rightarrow\overline{abc}=481000\div1480\)
\(\Rightarrow\overline{abc}=325\)
Vậy số cần tìm là 325
(481000 + abc) : abc = 1481
481000:abc + 1 = 1481
abc = 481000: 1480 = 325
