Question

Mr. Roboto has bought a can of paint can you use 3/8 of it to paint a bookshelf in use 1/4 of its pink leg and he used some of it to paint a birdhouse and he has one-eighth of it left how much paint do you use for the birdhouse?

Answer 1

Answer: Fraction of paint used for bird house =
`\frac14`

Explanation:

Let quantity of the total paint be 1.

Given: Fraction of paint to book shelf =
`\frac38`

Fraction of Paint to leg =
`\frac14`

Fraction of Paint left =
`\frac18`

Let x= fraction of paint used for bird house.

Total paint =
`\frac38 +\frac 14+\frac18+x=1`

`\Rightarrow\ (3+2+1)/(8)+x=1\\\\\Rightarrow\ (6)/(8)+x=1\\\\\Rightarrow\ x=1-\frac68\\\\\Rightarrow\ x=(2)/(8)=\frac14`

So, Fraction of paint used for bird house =
`\frac14`
