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:

$\begin{gathered} \frac{10}{100}=\frac{15}{x} \\ x=\frac{100\cdot15}{10} \\ x=150 \end{gathered}$

15 represents 150%, therefore:

$150-100=50$

The percentage with respect to the original is 50%.

$\frac{50}{100}=0.5$

form decimal = 0.5
