Write it as in the question!
1000 + 400 + 80 Hope this helped
It is 2.5*400 = 1000
1000*400=400000
400 + 1000 = 1400
400 percent of 1000 = 4000
0.4
Do you mean: 4,785,000 if so then it is ((CD))(DCCLXXXV) because it means 10*1000*400+1000*785 = 4,785,000
400
1000 + 400 - 300 = 1100
400 + 900 + 1000 = 2300
1000 g = 1 kg so 400 g = 400/1000 = 0.4 kg. Simple!
2/5 x 1000 = 400
