We are given that 18 is added to a number. If the number is "n", then we can write this mathematically as:


n+18

We are also given that the result is divided by 6. This is written as:


(n+18)/(6)

Now, we are given that the result is equal to 1/4 of the number plus 1, this is written as:


(n+18)/(6)=(1)/(4)n+1

Now, to determine the number we will solve for "n". First, we will distribute the denominator of the fraction on the left:


(1)/(6)n+(18)/(6)=(1)/(4)n+1

Now, we subtract n/4 from both sides:


(1)/(6)n-(1)/(4)n+(18)/(6)=(1)/(4)n-(1)/(4)n+1

Solving the operations:


-(1)/(12)n+(18)/(6)=1

Now, we simplify the fraction on the left side:


-(1)/(12)n+3=1

Now, we subtract 3 from both sides:


-(1)/(12)n+3-3=1-3

Solving the operations:


-(1)/(12)n=-2

Now, we multiply both sides by -12:


\begin{gathered} n=(-2)(-12) \\ n=24 \end{gathered}

Therefore, the number is 24.
