We need to find the percentage of the extra feet that she measured, so first we have to find out how much that is. We can do this by simply subtracting:
4.27 - 4 = 0.27
Now we can set up a proportion to find the percentage.
[tex] \frac{0.27}{4} \frac{x}{100} [/tex]
Solve for x
0.27 x 100 = 27
27/4 = 6.75
The answer is 6.75% :)
