Write it as in the question!
1000 + 400 + 80 Hope this helped
1000 times 400 equals 400,000.
It is 2.5*400 = 1000
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
400 + 900 + 1000 = 2300
1000 + 400 - 300 = 1100
1000 g = 1 kg so 400 g = 400/1000 = 0.4 kg. Simple!
2/5 x 1000 = 400
400 plus 1000 equals 1400. This is because when you add 400 and 1000 together, you are combining the two quantities to get a total sum of 1400. In mathematical terms, this operation can be represented as 400 + 1000 = 1400.
