S o l o m o n reads four pages of a book every 6 minutes which proportion could be solved to find x the number of minutes will take to read nine pages eight four over six equals x over 12 b 6/4 = 9/xc 604 = x over 90 4/10 = x over 9

The correct proportion to solve for x, the number of minutes it will take to read nine pages, is:

4/6 = 9/x

Cross multiplying, we get:

4x = 54

Dividing by 4 on both sides, we get:

x = 13.5

Therefore, it will take Solomon 13.5 minutes to read nine pages of the book.
