Answer 1

Step-by-step explanation:

To Find,

The length of half such piece in cm.

Solution,

Length of the string = 1 m

1 m = 100 cm

No. of parts to which the string is divided = 5

Measure of each part = \dfrac{100}{5}

5

100

= 20 cm

We have to find the half of the length of such a piece.

= \dfrac{20}{2}=10

2

20

=10

∴ The length of half of such a piece of string is 10 cm.
