Question

Roma gave a wooden board of length 150 1/4 cm to a carpenter for making a shelf. The Carpenter sawed off a piece of 40 1/5 cm from it. What is the length of the remaining piece

Answer 1

150 1/4 = 601/4

40 1/5 = 201/5

length of remaining piece = 150 1/4 - 40 1/5

= 601/4 - 201/5

= 2201/20 cm

I hope it helps u☺☺

Answer 2

The length of the remaining piece is 110¹/₂₀ cm

Given : Roma gave a wooden board of length 150 1/4 cm to a carpenter for making a shelf. The Carpenter sawed off a piece of 40 1/5 cm from it.

To find : The length of the remaining piece.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the length of the remaining piece)

Initial length of the wooden borad :

= 150¼ cm

$= \frac{(150 \times 4) + 1}{4} \: cm$

$= \frac{601}{4} \: cm$

Sawed off length :

= 40⅕ cm

$= \frac{(40 \times 5) + 1}{5} \: cm$

$= \frac{201}{5} \: cm$

Remaining length :

= Initial length - Sawed off length

$= ( \frac{601}{4} - \frac{201}{5}) \: cm$

$= ( \frac{3005 - 804}{20} )cm$

$= \frac{2201}{20} \: cm$

$= 110 \frac{1}{20} \: cm$

(This will be considered as the final result.)

Hence, the length of the remaining piece is 110¹/₂₀ cm
