gọi số cần tìm là abcde ,ta có  

abcde2= 2abcde x 3 ,phân tích cấu tạo số ra ta dc:  

100000a+10000b+1000c+100d+10e+2=600000+30000a+3000b+300c+30d+3e , rút gọn ta được :  

70000a+ 7000b+700c+70d+7e+2=600000 nên 70000a+ 7000b+700c+70d+7e=599998  

suy ra 7(10000a+1000b+100c+10d+e)=599998 nên 7abcde=599998

 suy ra abcde=85714

85714

Số đó là số 85 714 nhé bạn

Chúc bạn học tốt 😊😊😊

chữ cái thứ 2017 là chữ T

chữ T nhé

Bạn làm theo cách này nhé:

\(\frac{7}{5}\div\frac{4}{5}=\frac{7}{4}\)(5 ở trên tử và 5 ở dưới mẫu triệt tiêu còn 1)

Ta có: \(\frac{7}{4}>1>\frac{2005}{2006}\Rightarrow\frac{7}{4}\div\frac{4}{5}>\frac{2005}{2006}\)

7/5:4/5=35/20 nhẩm ra =7/4.Mà 7/4>1,2005/2006<1neen 7/5:4/5>2005/2006  Mik nghi ko đến 4s đâu
