Question

x:0,2+x:0,5+x:o,25+x:0,125=5,7

nhanh nhé các bạn mình cần gấp

Answer 1

\(\Rightarrow x:\left(0,2+0,5+0,25+0,125\right)=5,7\)

\(\Rightarrow x:1,075=5,7\)

\(\Rightarrow x=5,7.1,075=6,1275\)

Answer 2

x:(0,2+0,5) + (0,25+0,125)=5,7

x:0,7 + 0,375 = 5,7

x:1,075 = 5,7

x=5,7 X 1,075

x=6,1275

Answer 3

\(\frac{x}{0.2}+\frac{x}{0.5}+\frac{x}{0.25}+\frac{x}{0.125}=5.7\)

\(\frac{0.625x}{0.125}+\frac{0.25x}{0.125}+\frac{0.5x}{0.125}+\frac{x}{0.125}=\frac{0.7125}{0.125}\)

\(0.625x+0.25x+0.5x+x=0.7125\)

\(x\left(0.625+0.25+0.5+1\right)=0.7125\)

\(x=0.3\)
