151500 : 150 = 1010

15abc0 : abc = 1010

150000 + abc0 = 1010 x abc

150000 + 10 x abc = 1010 x abc

150000 = 1000 x abc ( Cùng bớt cả 2 vế đi 10 x abc )

150000 : 1000 = abc

150 = abc

abc = 150

Vậy a = 1 ; b = 5 ; c = 0

\(\overline{15abc0}:\overline{abc}=1010\)

\(150000+\overline{abc}.10:\overline{abc}=1010\)

\(1010.\overline{abc}=150000+\overline{abc}.10\)

\(1000.\overline{abc}=150000\)

\(\Rightarrow\overline{abc}=150\)

15abc0÷abc=1010

(15000+abc)×10÷abc=(100+1)×10

15000÷abc=100

abc=15000÷100

abc=150

Vậya=1;b=5;c=0

Đáp số:a=1;b=5;c=0

Đề là gì em?

a) abcabc + abc = 321642 

abc x 1001 + abc = 321321 + 321

-> abc = 321

b) 30abc : abc= 241

abc =125

c)15abc0 : abc =1010

abc = 150

d) 15abc : abc = 121

abc = 125

a) abcabc + abc = 321642

abc x 1001 + abc = 321321 + 321

=> abc = 321

b) 30abc : abc = 241

abc = 125

c) 15abc0 : abc = 1010

abc = 150

d) 15abc : abc = 121

abc = 125

15abc0 : abc = 1010

150000 + 10 x abc = 1010 x abc 

150000 = 1010 x abc - 10 x abc = 1000 x abc 

abc = 150000 : 1000 = 150

15abc0 : abc = 1010

=> 150 000 + 10 x abc = 1010 x abc

=> 150 000 = 1010 x abc - 10 x abc = 1 000 x abc

=> abc = 150 000 : 1 000 = 150

tao chiu

ta có:

15abc0:abc=1010

(150000+abcx10):abc=1010

150000:abc+abcx10:abc=1010

150000:abc+10=1010

      150000:abc=1010-10

      150000:abc=1000

           abc      =150000:1000

                  abc=150

Vậy abc=150 

thank you very much

\(15abc0\div abc=1010\)

\(\left(15000+abc\right)\times10\div abc=\left(100+1\right)\times10\)

\(15000\div abc=100\)

\(abc=15000\div100\)

\(abc=150\)

Vậy\(a=1;b=5;c=0\)

Đáp số:\(a=1;b=5;c=0\)

abc = 150           

15abc0:abc=1010

150000+abcx10=abcx1010

150000              =abcx1010-abcx10 (Rút gọn cả 2 vế cho abcx10)

150000              =abcx1000

                         => abc=150000:1000

                         => abc=    150

Vậy abc=150

                                       Đ/s: 150.

15abc0 : abc = 1010

15abc0 = abc x 1010

150000 + abc x 10 = abc x 1010

150000 = abc x 1010 - 10 

150000 = abc x 1000

=> abc = 150000 : 1000 = 150
