Question

3. A strip of wood 78 inches long is to be cut into pieces 3 3la inches long. How many pieces can be cut?

A. 21
B. 12
C. 26
D.20

Answer 1

Option D (20) is the right answer.

Explanation:

The given values are:

Length of wood,

= 78 inches

Wood pieces,

=
`3(3)/(4) \ inches`

On converting this in proper fraction, we get

=
`3(3)/(4)`

=
`(15)/(4)`

=
`3.75 \ inches`

Now,

On dividing "78" from "3.78", we get

=
`(78)/(3.75)`

=
`20.8 \ pieces`

So we got "20 pieces".
