Given the word problem, we can deduce the following information:
1. 3/5 of a number is 18.
To determine the number, we let x be the number and multiply it with 3/5. It is shown below:
![x((3)/(5))](https://img.qammunity.org/2023/formulas/mathematics/college/fw3auh4e89kbduif3carcmy75e83rc3cwc.png)
Then, to complete the equation, it would be like this:
![x((3)/(5))=18](https://img.qammunity.org/2023/formulas/mathematics/college/lnsm607lxszkxntltd26kmbhnwnoxa2w7b.png)
We simplify the equation:
![\begin{gathered} x((3)/(5))=18 \\ x=(18(5))/(3) \\ \text{Calculate} \\ x=30 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/ubb7fqm4hqeu33205nfbb3yn0ov12xgvwz.png)
Therefore, the number is 30.
