Answer: Fraction of paint used for bird house = [tex]\dfrac14[/tex]
Step-by-step explanation:
Let quantity of the total paint be 1.
Given: Fraction of paint to book shelf = [tex]\dfrac38[/tex]
Fraction of Paint to leg = [tex]\dfrac14[/tex]
Fraction of Paint left = [tex]\dfrac18[/tex]
Let x= fraction of paint used for bird house.
Total paint = [tex]\dfrac38 +\dfrac 14+\dfrac18+x=1[/tex]
[tex]\Rightarrow\ \dfrac{3+2+1}{8}+x=1\\\\\Rightarrow\ \dfrac{6}{8}+x=1\\\\\Rightarrow\ x=1-\dfrac68\\\\\Rightarrow\ x=\dfrac{2}{8}=\dfrac14[/tex]
So, Fraction of paint used for bird house = [tex]\dfrac14[/tex]
