BT1: Rút gọn
1) \(\frac{124.237+152}{870+235.122}\)
\(\frac{124.237+152}{870+235.122}\)
lắm rùi mà ?Announced the Upa and Polar 
(124.237+152):(870+235.122)
= 1
124.237 + 152 = 122. 237 + 2.237 + 152 = 122.235 + 2.122 + 474 + 152 = 122 .235 + 244 + 474 + 152 = 122 .235 870 : 870 + 235 .122 = 1
ddddddddddddddddddddddeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeooooooooooooooooooooooooooooooo
( 124.237 +152 ) : ( 870+235.122)
bằng 1 nha bạn.
Chúc bạn học giỏi nhoa!
(124.237 +152) : ( 870+235.122 )
=( 29388 +152) : (870+ 28670 )
= 29540 : 29540
= 1
h)(124.237 +152) : ( 870+ 235.122)
(124.237 +152) : ( 870+ 235.122)
= (29388 + 152 ) : ( 870 + 28670)
= 29540 + 29540
= 59 080

Answer : 1
(124.237+152):(870+235.122)
=(29388+152):(870+28670)
=29540:29540

(124.237 + 152): (870 + 235.122) ;
\((124.237+152):(870+235.122)\)
= \(\left(29388+152\right):\left(870+28670\right)\)
= \(29540:29540\)
= \(1\)
**Trả lời:
\(\left(124\cdot237+152\right):\left(870+235\cdot122\right)\)
\(=\left(29388+152\right):\left(870+28670\right)\)
\(=29540:29540\)
\(=1\).
