what is 238 workers to 200 workers
find the percent decrease round to nearest percent

Answer 1

8 out of 84: 90% decrease

200 out of 238: 16% decrease

Explanation:

To find a percent decrease, you first subtract the end number by the initial number. This gives you the change.

ex. 84-8=76

Now you divide the change by the initial number. You'll get a decimal.

ex. 76/84=0.904...

Multiply the decimal times 100, or move the decimal to the right twice.

ex. 0.904... -> 90.4...

Now round to the nearest ones place

ex. 90.4 -> 90%
