Solution

Find the expression:
Given that, Emily is thinking of a number, which she calls $n$ . She finds $\frac{1}{4}$ of the number and then subtracts $3$ .
Here, if the Emily thinks a number that is $n$ after that she finds $\frac{1}{4}$ of the number that is $\frac{1}{4} n$ .
If then substracts $3$ from that number that is $\frac{1}{4} n - 3$ .
Hence, the expression which represents Emily's number is $\frac{1}{4} n - 3$ .
