A 700px grid has columns 200px 1fr 2fr and a 20px gap between each pair. How is flexible space divided?

1. The two flexible tracks divide the remaining 460px in a 1:2 ratio.
2. They receive one third and two thirds of the full 700px.
3. Each fr always equals 100px.
4. The gaps are subtracted from the 200px track only.
