So its: 2.9 – 2.7

Then you take the answer, .2, and you divide it by the ACTUAL Value.

It looks like:

.2

______

2.7

= .074 ?

Whatever that equals you take it and THEN multiply it to 100%

7.4 equals your percent value

Correct?

First find the Absolute Error.

E= |0-A| O= observed value (your measurement)

A= actual value (correct answer)

So in your case. E= |2.9-2.7|

.2

Now Find Percent Error.

P= E/A x 100

E= Absolute Error

A= Actual Value.

So. .2/ 2.7 x 100

Which equals 7 %.
