1/2:0,5 - 1/4 ; 0,25 + 1/8 : 0,125 - 1/10 ; 0,1
= 0,5 : 0,5 - 0,25 : 0,25 + 0,125 : 0,125 - 0,1 : 0,1
= 1 - 1 + 1 - 1
= 0 + 1 - 1
= 1 - 1
= 0
Lời giải:
$=\frac{1}{2}\times 2-\frac{1}{4}\times 4+\frac{1}{8}\times 8-\frac{1}{10}\times 10$
$=1-1+1-1=0$

\(13,25:0,75+13,25:0,25+13,5:0,325\)
\(=13,25:\left(0,75+0,25+0,325\right)\)
\(=13,25:1,325\)
\(=10\)
\(\dfrac{1}{4}:0,25-\dfrac{1}{8}:0,125+\dfrac{1}{2}:0,5-\dfrac{1}{16}:0,0625\)
\(=\dfrac{1}{4}:\dfrac{1}{4}-\dfrac{1}{8}:\dfrac{1}{8}+\dfrac{1}{2}:\dfrac{1}{2}-\dfrac{1}{16}:\dfrac{1}{16}\)
\(=1-1+1-1\)

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