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

500 + 100 = 100 + 500
300 + 200 = 300 + 200
400 + 200 = 200 + 400
500+x=100+500
vay x =100
300-x=300+200
vay x= - 200
400-x=200+400
vay x= -200
Tìm X,biết:
100 + 100 < 300 - X < 200 + 200
X=0
Tick nha !Nguyễn Khánh Duy
x+100=200+300
x-100=200
ai k mk
x + 100 = 200 + 300
x + 100 = 500
x = 500 - 100
x = 400
x - 100 = 200
x = 200 + 100
x = 300
x+100=200-200+100-100+300
ai k mk ru mk k lai
x+100=200-200+100-100+300
x+100=300
x=300-100
x=200
tk mk mk tk lại
x + 100 = 200 - 200 + 100 - 100 + 300
x + 100 = 300
x = 300 - 100
x = 200
Vậy số tự nhiên x cần tìm là 200
x+100=200-200+100-100+300
x+100=0+0+300
x-200=0+300
x-200=300
x=300+200
x=500
100+100+200+200+300+300=
100 + 100 + 200 + 200 + 300 + 300
= 200 + 200 + 200 + 300 + 300
= 400 + 200 + 300 + 300
= 600 + 600
= 1200
