Question

x + x : 0,25 + x : 0,5 + x : 0,125 = 0,45

Answer 1

`x+x:0,25+x:0,5+x:0,125=0,45`

`=>x+x xx 4+x xx 2+x xx 8=0,45`

`=> x xx (1+4+2+8)=0,45`

`=> x xx 15=0,45`

`=> x =0,45:15`

`=>x=0,03`

Answer 2

\(x+x:0,25+x:0,5+x:0,125=0,45\)
\(x\times1+x\times4+x\times2+x\times8=0,45\)
\(x\times\left(1+4+2+8\right)=0,45\)
\(x\times15=0,45\)
\(x=0,45:15\)
\(x=0,03\)

Answer 3

x+x:1/4+x:1/2+x:1/8 bằng 0.45

X+X x 4+ X x 2+ X x 8 bằng 0.45

x+4x+2x+8x bằng 0.45

15x bằng 0.45

x bằng 0.45/15 bằng 0.03
