Answer:

12

Step-by-step explanation:

Let x be the number we are looking for. Using informations in the task, we get following equation which we suppose to solve for x

[tex]2\frac{1}{4} x=27[/tex]

Now, we will write mixed number as a fraction and get

[tex]\frac{9}{4} x=27[/tex]

In the next step, we will multiply both sides of the equation by 4 and get

[tex]9x=27*4\\x=\frac{27*4} {9}\\x=12[/tex]

So, required number is 12.
