x+200+200=200+200+100
x+200+200=200+200+100
x+400=500
x=500-400
x=100
tk minh nha
X+200+200=200+200+100
X+(200+200)=500
X+400=500
X=500-400
X=100
x + 200 + 200 = 200 + 200 + 100
x + 400 = 500
x = 500 - 400
x = 100
100+100+200+200
100 + 100 + 200 + 200
= 200 + 200 + 200
= 200 x 3
= 600
tk mk nha
hihi <3
100 + 100 + 200 + 200
= ( 100 x 2 ) + ( 200 x 2)
= 200 + 400
= 600
100+100+200+200+300+300=
100 + 100 + 200 + 200 + 300 + 300
= 200 + 200 + 200 + 300 + 300
= 400 + 200 + 300 + 300
= 600 + 600
= 1200
100 + 100 =
200 + 200 =
Trả lời:
100 + 100 = 200
200 + 200 = 400
Hok tốt!

Tính.
a) 200 mm + 100 mm 300 mm – 100 mm 200 mm x 3 600 mm : 3
b) 300 g + 200 g 200 g × 5 500 g – 300g 1000g : 5
c) 400 ml + 300 ml 800 ml : 4 700 ml – 300 ml 200 ml x 4
a) 200 mm + 100 mm = 300 mm 300 mm – 100 mm = 200 mm |
200 mm x 3 = 600 mm 600 mm : 3 = 200 mm |
b) 300 g + 200 g = 500 g | 200g x 5 = 1 000g | 500g – 300g = 200g | 1 000g : 5 = 200g |
c)
400 ml + 300 ml = 700 ml
800 ml : 4 = 200 ml
700 ml – 300 ml = 400 ml
200 ml x 4 = 800ml
100 + 200 - 4000 + 3000 + 100 - 200 + 300 =
100 + 200 - 4000 + 3000 + 100 - 200 + 300 = [(100+100)+(200-200)+(3000+300)]-4000
= [200+3300] -4000
= 3500-4000
= -500
ủng hộ mk nha mấy bn
âm 500 suy ra viết là: -500
x + 100 +100 +200 = 200
X+100+100+200=200
X+(100+100+200)=200
X+400=200
X=200-400
X=-200
x + 100 + 100 + 200 = 200
x = 200 - 200 - 100 - 100
x = - 200
x + 100 + 100 + 200 = 200
x = 200 - 200 - 100 - 100
x = -200
tính nhanh :
100 x 200 + 200 x 500 + 200 x 400
100x200+200x500+200x400
=20000+100000+80000
=120000+80000
=200000
100 x 200 + 200 x 500 + 200 x 400
= 200 x ( 100 + 500 + 400 )
= 200 x 1000
= 200000
100x200+200x500+200x400
=20000+100000+80000
=120000+80000
=200000
