Hi,
This is part of a project abstract. I want to say that there are three treatments (levels of the the ratios) but I am unsure about the prepositions here:
1. The ratios of brown rice flour and rice flour were varied at three levels: 60:40 70:30 and 80:20.
2. The ratios of brown rice flour and rice flour were varied by three levels at 60:40 70:30 and 80:20.
Which one looks better?
I didn't want to put another at in 1. because it looks repetitive, so I used a colon instead.
Thank you.
