341 x 67 + 341 x 16 + 659 x 83
= 341 x (67 + 16) + 659 x 83
= 341 x 83 + 659 x 83
= (341 + 659) x 83
= 1000 x 83
= 83000
341 x 67 + 371 x 16 + 659 x 83
= 22847 + 5936 + 54697
= 83480
341*67+341*16+659*83
=341*(67+16)+659*83
=341*83+659*83
=89*(341+659)
=89*1000
=89000
\(77+54+967+946+5033=\left(967+5033\right)+\left(946+54\right)+77=6000+1000+77=7077\)
\(341.67+341.16+659.83=341\left(67+16\right)+659.83=341.83+659.83=83\left(341+659\right)=83.1000=83000\)
b: Ta có: \(341\cdot67+341\cdot16+659\cdot83\)
\(=341\cdot83+659\cdot83\)
=83000
a)\(341\times67+341\times16+659\times83=\left[341\times\left(67+16\right)\right]+659\times83\)
\(=341\times83+659\times83=83\times\left(341+659\right)=83\times1000=83000\)
b)\(30\%\times x+x=52\Rightarrow\frac{3}{10}\times x+x=52\Rightarrow x\times\left(\frac{3}{10}+1\right)=52\)
\(\Rightarrow x\times1,3=52\Rightarrow x=52:1,3\Rightarrow x=40\)
c)\(75\%\times x+\frac{3}{4}\times x+x=30\Rightarrow\frac{3}{4}\times x+\frac{3}{4}\times x+x=30\Rightarrow x\times\left(\frac{3}{4}+\frac{3}{4}+1\right)=30\)
\(\Rightarrow x\times\frac{5}{2}=30\Rightarrow x=30:\frac{5}{2}\Rightarrow x=12\)
314,12 + 78: X x 2,24 = 341
78: X x 2,24 = 341- 314,12
78: X x 2,24 = 26,88
78: X = 26,88: 2,24
78: X = 12
X = 78: 12
X = 6,5
78:Xx2,24=341-314,12
78:Xx2,24=26,88
78:x=26,88:2,24
78:x=12
x=78:12
x=6,5
341×67+341×16+65×83
=341×(67+16)+65×83
=341×83+65×83
=(341+65)×83
=406×83

k mik nha
341 x 67 + 341 x 16 + 65 x 83
=341 x ( 67 + 16 ) + 65 x 83
=341 x 83 +65 x 83
=83 x 341 +65
=28303 + 65
= 28368
tk + kb nha ! hok tốt !
341x67+341x16+65x83
=341x(67+16)+65x83
=341x83+65x8
=406x83
=33698
TlCK nha
341.67 + 314 . 16 + 65 . 83
= 341.( 67 + 16 ) + 65 . 83
= 341. 83 + 65 . 83
= 83 . ( 341 + 65 )
= 83 . 406
= 33 698
Hok tốt nha bn !!!
\(341.67+341.16+65.83\)
\(=341.\left(67+16\right)+65.83\)
\(=341.83+65.83\)
\(=83.\left(341+65\right)\)
\(=83.406\)
\(=33698\)
341 x 67 + 341 x 16 + 65x 83
= 341 x (67 + 16) + 65 x 83
= 341 x 83 + 65 x 83
= 83 x (341 + 65)
= 83 x 406
= 33698
341 . 67 + 341 . 16 + 65 . 83
= [ 341 . ( 67 + 16 ) ] + 65 . 83
= 341 . 83 + . 65 .83
= ( 341 + 65 ) . 83
= 406 . 83
= 33698
Đáp án:
= 33 698
Học tốt!
