Question

X÷0,5x÷0,25+x÷0,125=3,75

 

Answer 1

\(x\div0,5+x\div0,25+x\div0,125=3,75\)

\(\Leftrightarrow2x+4x+8x=3,75\)

\(\Leftrightarrow x\left(2+4+8\right)=3,75\)

\(\Leftrightarrow14x=3,75\)

\(\Leftrightarrow x=\frac{3,75}{14}\)

\(\Leftrightarrow x=0,2678571\)

\(\text{Vậy }x=0,2678571\)

Answer 3

\(x\text{ : }0,5+x\text{ : }0,25+x\text{ : }0,125=3,75\)

\(x\text{ x }2+x\text{ x }4+x\text{ x }8=3,75\)

\(x\text{ x }\left(2+4+8\right)=3,75\)

\(x\text{ x }14=3,75\)

\(x=3,75\text{ : }14\)

\(x=\frac{3,75}{14}=0,267857143\)

Answer 4

\(x:0,5+x:0,25+x:0,125=3,75\)

\(2x+4x+8x=3,75\)

\(x\left(2+4+8\right)=3,75\)

\(14x=3,75\)

\(x=\frac{3,75}{14}\)

\(\Rightarrow x=0,2678571\)

\(V\text{ậy}\)\(x=0,2678571\)
