= 2145 : 1000 - 2145 : 1000 / 2,5 x 6,6 x 4 = 0 / 2,5 x 6,6 x 4 = 0
Tk mk nha

214,5 : 100 - 2145 : 1000
= 2,145 - 2,145
= 0
2,5 x 9,6 x 4
= ( 2,5 x 4 ) x 9,6
= 10 x 9,6
= 96

0,75.6,25.32=150
214,5:100-2145:1000=0
25.96.4=9600
. là dấu nhân

a) \(x+657=1657\)
\(\Rightarrow x=1657-657\)
\(\Rightarrow x=1000\)
b) \(4059+x=7876\)
\(\Rightarrow x=7876-4059\)
\(\Rightarrow x=3817\)
c) \(x-1245=6478\)
\(\Rightarrow x=6478+1245\)
\(\Rightarrow x=7723\)
d) \(6535-x=4725\)
\(\Rightarrow x=6535-4725\)
\(\Rightarrow x=1810\)
a) \(x+657=1657\)
\(x=1657-657\)
\(x=1000\)
b) \(4059+x=7876\)
\(x=7876-4059\)
\(x=3781\)
c) \(x-1245=6478\)
\(x=6478+1245\)
\(x=7723\)
d) \(6535-x=4725\)
\(x=6535-4725\)
\(x=1810\)

b) 18,3*(2,1+3,9)
=18,3* 6
= 109,8
c) 32,4*(6,34+3,66)
= 32,4* 10
= 324
d)17,2*(8,55+0,45)
= 17,2* 9
= 154,8


8×2145+1765×8-8×678
=17160+14120-5424
=31280-5424
=25856

x : 5 = 2145 ( du 3 )
x = 2145 x 5 + 3
x = 10725 + 3
x= 10728
k nha
