= 1/2 : 1/2 - 1/4 : 1/4 + 1/8 : 1/8 : 1/10
= 1 - 1 + 1 : 0,1
= 0 + 10
= 10
k mk nha !
\(\frac{1}{2}:0,5-\frac{1}{4}:0,25+\frac{1}{8}:0,125:0,1\)
\(=\frac{1}{2}\times2-\frac{1}{4}\times4+\frac{1}{8}\times8\times10\)
\(=\frac{2}{2}-\frac{4}{4}+\frac{8}{8}\times10\)
\(=1-1+1\times10\)
\(=0+10\)
\(=10\)
\(\frac{1}{2}\div0,5-\frac{1}{4}\div0,25+\frac{1}{8}\div0,125\div0,1\)
\(=0,5\div0,5-0,25\div0,25+0,125\div0,125\div0,1\)
\(=1-1+1\div0,1\)
\(=1\times10\)
\(=10\)
Học tốt nhé bạn !
1/2 : 0,5 - 1/4 : 0,25 + 1/8 : 0,125 : 0,1
= 1/2 : 1/2 - 1/4 : 1/4 + 1/8 : 1/8 : 0,1
= 1 - 1 + 1 : 0,1
= 0 + 10
= 10

1/2 : 0,5 -1/4 :0,25 +1/8 :0,125 : 0,1
=0,5 : 0,5 - 0,25 :0,25 + 0,125 :0,125 : 0,1
= 1 - 1 + 1 :0,1
= 0+ 10
=10
