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

Serhud [2]

Answer:

$\frac{51}{10}$ m

Step-by-step explanation:

Given parameters:

Length of rope = 11m

First length cut off = $\frac{13}{5}$ m

Second length cut off = $\frac{33}{10}$ m

Unknown:

Remaining length = ?

Solution:

Let us find the total length cut off first;

= $\frac{13}{5}$ m + $\frac{33}{10}$ m

= $\frac{26 + 33}{10}$

= $\frac{59}{10}$ m

So,

Remaining length = 11 - $\frac{59}{10}$

= $\frac{110 - 59}{10}$

= $\frac{51}{10}$ m
