Answer:
2%
Step-by-step explanation:
True measurements = 400 meters
Observed measurements = 392 meters
% error = change in measurements / true measurements × 100/1
= (400 - 392) / 400 × 100
= 8/400 × 100
= 0.02 × 100
= 2%
Percentage error of Beth measurements = 2%
Answer:
The question
after change the mixed number to improper & using KCF will become : 
Option B is correct option.
Step-by-step explanation:
We need to change the mixed number to improper & use KCF to rewrite the question.
The expression is: 
First converting mixed fraction into improper fraction
Multiply whole number with the denominator i,e (3*2=6) now add the numerator i.e (6+1) = 7/2
Solving:

Using KCF
KCF stands fro Keep it, Change it, Flip it.
It is used when division sign is converted to multiplication the term (1/3) is reversed to (3/1)
So, our expression will be

So, The question
after change the mixed number to improper & using KCF will become : 
Option B is correct option.
First turn 28 kilograms into pounds by multiplying 2.2 by 28. You end up with 61.6 pounds lost in one week. Next you take 61.6 divided by 7 to know how many pounds were lost in each day. You should end up with about 8.8 pounds.
