There are 10 doses. 4x5=20/2=10

In order to find the answer to this problem, you want to divide 4 by 2/5. To do this, you do the following:
Put 4 over 1, so it looks like 4/1. Now, you have the equation 2/5 * 4/1. Multiply the top by the top, and the bottom by the bottom. 2 * 4 is 8, and 5 * 1 is 5. So now you have 8/5. You don't stop here, instead you need to make it a mixed fraction. To do that, you divide the bottom into top. 8 divided by 5 is 1, and you have 3 left over. You take that 3 and put it over 5 because before you divided, 5 was your denominator.

How are percent error and percent change similar

mihalych1998 [28]

Percent Change = New Value − Old Value|Old Value| × 100%

Example: There were 200 customers yesterday, and 240 today:

240 − 200|200|× 100% = 40200 × 100% = 20%

A 20% increase.

Percent Error = |Approximate Value − Exact Value||Exact Value| × 100%

Example: I thought 70 people would turn up to the concert, but in fact 80 did!

|70 − 80||80| × 100% = 1080 × 100% = 12.5%

I was in error by 12.5%

(Without using the absolute value, the error is −12.5%, meaning I under-estimated the value)

The difference between the two is that one states factual calculations and the other is a theoretical guess
