Tina had 20 m 5 cm long cloth. She cuts 4 m 50 cm length of cloth from this for making a curtain. How much cloth is left with her?

Given:

Tina had 20 m 5 cm long cloth. She cuts 4 m 50 cm length of cloth from this for making a curtain. 

To do:

We have to find the length of the cloth left with her.

Solution:

We know that,

$1\ m=100\ cm$

Length of the cloth Tina had $= 20\ m\ 5\ cm$

$=(20+\frac{5}{100})\ m$

$=(20+0.05)\ m$

$= 20.05\ m$

Length of the cloth required to make the curtain $= 4\ m\ 50\ cm$

$=(4+\frac{50}{100})\ m$

$=(4+0.5)\ m$

$= 4.5\ m$

Therefore,

The length of the cloth left with Tina $=$ Length of the cloth Tina had $-$ Length of the cloth required to make the curtain

$=20.05\ m-4.5\ m$

  $20.05$

$-4.50$

------------

  $15.55$

-----------

The length of the cloth left with Tina is $15.55\ m$.
