Question

Using half , three quarters
A rope has a length of 16 meters . if a three quarter length is to be cut off. What length should be marked off from one end ?

Answer 1

Ans: 4 m
three quarter of 16 = 3/4 (16) = 12 m
so remaining is 16 - 12 = 4 m

Answer 2

Given:

A rope of length 16 meters.

To Find:

The length which should be marked off from one end, if three-quarter length is to be cut-off.

Solution:

Since, 1 quarter = $\frac{1}{4}$

$\therefore$ 3 quarters = $3 \times \frac{1}{4} = \frac{3}{4}$

Now, from 16 meters rope, $\frac{3}{4}th$ length is to be cut-off, so we shall find the length (in meters) that is to be cut-off.

Length of rope that is to be cut-off = $\frac{3}{4} \times 16 = 3 \times 4 = 12 \ m$

Now, we have to mark from the other end of the rope.

So, length which should be marked = 16 - 12 = 4 meters.

Therefore, There should be a mark at 4 meters from the other end of the rope.
