Question

If 10 is increased to 15, the increase is what percent of the original number? (This is known as the percent change.)Answer = Write your resulting percent in decimal form with three decimal places of accuracy. Example: Write 2% as 0.02. Write 5.66% as 0.057.

Answer 1

we have the following:

`\begin{gathered} (10)/(100)=(15)/(x) \\ x=(100\cdot15)/(10) \\ x=150 \end{gathered}`

15 represents 150%, therefore:

`150-100=50`

The percentage with respect to the original is 50%.

`(50)/(100)=0.5`

form decimal = 0.5
