Set up the equation like this 9. X ________ = _________ 12. 1
X is the amount of cups of water 1 is the amount of flour you want to have in the end
To solve you must solve for x 1. Cross multiply 9×1 2. Cross multiply 12×X You should end up with it looking like this 9=12X Then solve for X 1. Divide 9 by 12 That should get you your answer.
If that is to complicated you can just divide 9 by twelve, but that way is esier for solving for other things.
