Answer:

Step-by-step explanation:
Given
The second fret is
from the first fret.
The third fret is
from the second fret.
Distance of third fret from the first fret
Distance from first fret to second fret
Distance from second fret to third fret.

Hence, we can see the third fret is
from the first fret.
Y = 2
y/4 + 2/3 = y/3 + 1/2
2/4 = 1/2
2/3 = 2/3
2/4 + 2/3 = 2/3 + 1/2
8.01-(2.2+4.67) ->
8.01-(6.87) ->
1.14 is the answer.
