Question

x : 0,25 + x : 0,5 + x : 0,125 = 24

Answer 1

x : 0,25 + x : 0,5 + x : 0,125 = 24

\(x\) x 4 + \(x\) x 2 + \(x\) x 8 = 24

\(x\) x (4 + 2 + 8) = 24

\(x\) x 14 = 24

x = 24 : 14

x = 1(dư 10)

Answer 2

Lời giải:

$x:0,25+x:0,5+x:0,125=24$

$x\times 4+x\times 2+x\times 8=24$

$x\times (4+2+8)=24$

$x\times 14=24$

$x=24:14=\frac{12}{7}$

Answer 3

\(x:0,25+x:0,5+x:0,125=24\)

\(x\times4+x\times2+x\times8=24\)

\(x\times\left(4+2+8\right)=24\)

\(x\times14=24\)

\(x=24:14\)

\(x=\dfrac{12}{7}\)
