Last month, steven had $4285.68 that he divided into two accounts. he deposited 1/3 into a savings account. he deposited the rest into his checking account. how much money did steven deposit into his checking account?

So, the first thing that you have to do is figure out what fraction of the money Steven deposited in his checking account.  If he deposited 1/3 into his savings account, you would subtract that fraction from the whole (1) to get 2/3.  

Now, you know that Steven deposited 2/3 of $4285.68 into his checking account.  You multiply these two things together, to find the total amount Steven deposited in his checking account.

2/3 * 4285.68 = 2857.12

Your final answer is that Steven deposited $2857.12 into his checking account.
