Emily is thinking of a number, which she calls n. She finds 1/4 of the number and then subtracts 3.

n/4 - 3 OR 1/4n - 3

Step-by-step explanation:

First, let's assign a variable to Emily's number.  Let is be x.

Now all we have to do is go through the problem step by step.

"She finds 1/4 of the number..."

There are two ways you can do this.  You can either multiply n by 1/4 (1/4n), or you can divide by 4 (dividing by four is the same as finding 1/4 of a number).  For this example let's divide by four

n/4

"...and then subtracts 3."

All we have to do is subtract 3 from n/4

n/4 - 3

REMEMBER: like I said, there are two possible options.  You can either have n/4 or 1/4n. They mean the same thing
