Question

45%of what is 81 can you write the answer out so I can see the steps

Answer 1

Step 1:

In this question, we are meant to solve the following:

45%of what is 81?

Step 2:

Let the unknown number be x, such that:

`\begin{gathered} 45\text{ \% of x = 81} \\ (45)/(100)\text{ of x = 81} \\ \\ (45x)/(100)=81 \\ \end{gathered}`

Cross-multiply, we have that:

`\begin{gathered} 45x\text{ = 8100} \\ \text{Divide both sides by 45, we have that:} \\ \text{x =}(8100)/(45) \\ x\text{ = 180} \end{gathered}`

CONCLUSION:

The final answer is:

`x\text{ = 180}`
