Question

From a rope 11m long two pieces of lengths 13/5m and 33/10m are cut off. What is the length the remaining rope?

Answer 1

`(51)/(10)`m

Explanation:

Given parameters:

Length of rope = 11m

First length cut off =
`(13)/(5)`m

Second length cut off =
`(33)/(10)`m

Unknown:

Remaining length = ?

Solution:

Let us find the total length cut off first;

=
`(13)/(5)`m +
`(33)/(10)`m

=
`(26 + 33)/(10)`

=
`(59)/(10)`m

So,

Remaining length = 11 -
`(59)/(10)`

=
`(110 - 59)/(10)`

=
`(51)/(10)`m
