How do you write the number 314,207 in expanded form?

Three hundred thousand fourteen two hundred and seven

300,000+10000+4,000+200+7

Base on the question which is asking to calculate the value if H, which the point is in the segment and has an end of B(3,-1) and Z(12,5) and the segment partition would be 5:1, base on my calculation, the value of H would be (10.5, 4). I hope you are satisfied with my answer and feel free to ask for more
