Question

Part A. 0.3 is 30% of what number ?

Answer 1

Let be "x" the number that represents 100%.

According to the information given in the exercise, 30% of the number "x" is:

`0.3`

Then, you can set up the following proportion:

`(0.3)/(30)=(x)/(100)`

Now you can solve for "x" in order to find the number:

`\begin{gathered} (100)((0.3)/(30))=x \\ \\ (30)/(30)=x \\ \\ x=1 \end{gathered}`

Therefore, the answer is:

`1`
