\(1000:x\cdot5=267+438\)
\(1000:x\cdot5=705\)
\(1000:x=141\)
\(x=\frac{1000}{141}\)
vậy........
1000 : X x 5 = 276+438
1000: X x 5 = 705
1000 : X = 705 : 5
1000 : X = 141
X = 1000 : 141
X = \(\frac{1000}{141}\)
1000:x x 5=267+438
1000:x x 5=705
1000:x=705:5
1000:x=141
x=1000:141
x=0,141
\(1000\div x\times5=267+438\)
\(1000\div x=705\div5\)
\(1000\div x=141\)
\(x=141\div1000\)
\(x=0,141\)
1000:Xx5=705
=1000:X=705:5
=1000:X=141
=1000:141
=?
(tự biết nhé) :)
1000: X x 5 = 267+ 438
1000: X x 5 = 705
1000: X = 750 : 5
1000: X = 150
X = 1000: 150
X = 6 dư 100
