Question

Find the percent of decrease from 80 to 60.

Question 2 options:

60% decrease


30% decrease


100% decrease


25% decrease

Answer 1

To find the percent of decrease from 80 to 60, you can use the following formula:

\[
\text{Percent Decrease} = \left( \frac{\text{Original Value} - \text{New Value}}{\text{Original Value}} \right) \times 100
\]

In this case, the original value is 80 and the new value is 60. Plugging in the numbers:

\[
\text{Percent Decrease} = \left( \frac{80 - 60}{80} \right) \times 100 = \left( \frac{20}{80} \right) \times 100
\]

Calculating the fraction:

\[
\frac{20}{80} = 0.25
\]

Now multiply by 100 to convert to a percentage:

\[
0.25 \times 100 = 25\%
\]

Thus, the percent of decrease from 80 to 60 is **25% decrease**.

So, the correct answer is:
**25% decrease**.
