Answer 1

Please help.

Answer 2

Don't give answer i want to learn.

Answer 3

Okay so first of all: Subtract Approximate value from Exact value.
Then the answer you get is then divided by the exact value (or correct measurement in your case).

Answer 4

Make sure that since you are talking about two different types of measurement, you change it to either both in foot or feet.

Answer 5

Also after you divide it by the exact value, remember, "percentage" you have to multiply by 100 to make it a percentage. ;p

Answer 6

So 4.00 - 4.27 = .27. .27 divided by 4.00 x 100?

Answer 7

yes, that's the correct sequence you go through, but remember, they are measured in different units, so you might have to convert both values to either feet or foot.

Answer 8

Ok

Answer 9

but you are correct, just change the units and your good ;p Hope I helped.
