1/90:0.25+1/90:0.5+1/90:0.125-1/90:0.1

= 1/90 x 4 + 1/90 x 5 + 1/90 x 2 + 1/90 x 8 - 1/90 x 10

= 1/90 x ( 4+5+2+8-10)

= 1/90 x 9

= 1/10

k nha!Cảm ơn nhiều!

1/2 : 0.5 - 1/4 : 0.25 + 1/8 : 0.125 - 1/10 : 0. 1

= 1 - 1  +  1 - 1

= 0 + 0

= 0

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

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

\(=1-1+1-1=0\)

bằng 0

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

=1-1+1-1

=0

`25%+3/4+1/2:0,5-1/4:0,15+1/8:0,125`

`=1/4+3/4+1/2xx2-1/4xx4+1/8xx8`

`(1/4+3/4)+(1/2xx2)-(1/4xx4)+(1/8xx8)`

`=1+1-1+1`

`=2`

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

= 1 - 1 + 1 - 1

=      0 + 0

=         0

1/2 : 0.5 - 1/4 : 0.25 + 1/8 : 0.125 - 1/10 : 0.1

= 1 - 1 + 1 - 1

= 0 + 0

= 0

1/2 : 0.5 - 1/4 : 0.25 + 1/8 : 0.125 - 1/10 : 0.1 = 1

đồng ý vứi mình thì k nhé
