Answer:
percentage error = 12.28%
Step-by-step explanation:
5 x 0.14 = 0.7
5 x 1.14 = 5.7
as increase is not the same as error decrease.
We use the same numbers 12.28% = 0.1228.
5.7 x 0.1228 = 0.69996  = 12.28%
5.7 - 0.69996 = 5.00004 foot.  As decrease.
And find it is correct.
His error therefore was 12.28% out.
As we work the first numbers 5.7 and can only x by a number to see 5ft
We take 5.7 x 0.1228 and find  0.69996 when taken from 5.7 ft. is unmistakably 5 foot.  (5.00004) ft.
 
        
                    
             
        
        
        
7/15 ÷ 3/5 =
= 7/15 * 5/3 =
= 7/3 * 1/3 =            (after simplifying)
= <u>7/9</u>
Correct answer: A
Just keep in mind that dividing one fraction by another fraction is as much as multiplying the same fraction by an inverse of the second one.
