Total length of the string =
yard
Length of string used for craft =
of total length of string
=
of 
= 
=
yard
Length of the string left after use = Total length of the string - Length of string used for craft
Length of the string left after use = 
=
Reducing it to the lowest term, we get
=
yard
Therefore, the length of string left is
yard.
1/12 or decimal form 0.083 with repeating line
I think its 3 - (0,10, 42)
if you put in the values of the given x, then these are the resulting y values.
The constant of proportionality is 5/9
y= kx where k is the constant of proportionality
y = 5/9 x
k = 5/9
