\(10:0,5+4:0,25+8:0,125\\ =10:\dfrac{1}{2}+4:\dfrac{1}{4}+8:\dfrac{1}{8}\\ =10\times2+4\times4+8\times8\\ =20+16+64\\ =20+\left(16+64\right)\\ =20+80\\ =100\)

Cop ko bt nhục 

 1/2;0,5-1/4:0,25+1/8:0,125-1/10:0,1

=1-1+1-1

=0+0

=0

nhớ k cho mik vs bạn nhé

mình ko hiểu lắm bạn có thể viết đầy đủ được ko

1/2÷0,5-1/4÷0,25+1/8:0,125-1/10:0,1=0

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

# Chúc em học tốt 

10: 0,5 + 4 : 0,25 + 8 : 0,125

= 10 x 2 + 4 x 4 + 8 x 8

= 2 x ( 10 + 8 + 32)

= 2 x 50

= 100 

e cảm ơn cj nhiều ạ

=1/4:1/4-1/8:1/8+1/2:1/2-1/10

=1-1+1-1/10

=1-1/10

=9/10

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

`=1/4 : 1/4 - 1/8 : 1/8 + 1/2 :1/2 - 1/10 `

`=1/4 . 4/1 - 1/8 . 8/1 + 1/2 . 2/1 - 1/10`

` = 1  - 1 + 1 - 1/10 `

`=  1 - 1/10 `

`= 10/10 - 1/10 `

`=9/10`

\(=\dfrac{1}{4}:\dfrac{1}{4}-\dfrac{1}{8}:\dfrac{1}{8}+\dfrac{1}{2}:\dfrac{1}{2}-\dfrac{1}{10}\)

\(=1-1+1-\dfrac{1}{10}\)

= 0,9

\(\dfrac{1}{4}:0,25-\dfrac{1}{8}:0,125+\dfrac{1}{2}:0,5-\dfrac{1}{10}\\ =\dfrac{1}{4}:\dfrac{1}{4}-\dfrac{1}{8}:\dfrac{1}{8}+\dfrac{1}{2}:\dfrac{1}{2}-\dfrac{1}{10}\\ =1-1+1-\dfrac{1}{10}\\ =\left(1-1\right)+\left(1-\dfrac{1}{10}\right)\\ =1-\dfrac{1}{10}\\ =\dfrac{10-1}{10}=\dfrac{9}{10}\)

\(\dfrac{1}{4}:0,25-\dfrac{1}{8}:0,125+\dfrac{1}{2}:0,5-\dfrac{1}{10}:0,1\)

\(=\dfrac{1}{4}:\dfrac{1}{4}-\dfrac{1}{8}:\dfrac{1}{8}+\dfrac{1}{2}:\dfrac{1}{2}-\dfrac{1}{10}:\dfrac{1}{10}\)

\(=1-1+1-1\)

\(=0\)

\(\dfrac{1}{4}:0,25-\dfrac{1}{8}:0,125+\dfrac{1}{2}:0,5-\dfrac{1}{10}:0,1\)

\(=\dfrac{1}{4}\times4-\dfrac{1}{8}\times8+\dfrac{1}{2}\times2-\dfrac{1}{10}\times10\)

\(=\dfrac{4}{4}-\dfrac{8}{8}+\dfrac{2}{2}-\dfrac{10}{10}\)

\(=1-1+1-1\)

\(0\)

=1/2:1/2-1/4:1/4+1/8:1/8-1/10:1/10+5/4

=1/2x2-1/4x4+1/8x8-1/10x10+5/4

=     1  -     1   +    1   -    1+5/4

=            5/4

cảm ơn bạn nhiều
