It takes 17 full specific type of trees to make one tonne of paper. If there are 221 such trees in a forest, then

(i) what fraction of forest will be used to make;

A. 5 tonnes of paper.

B. 10 tonnes of paper.

(ii) To save part of the forest how much of paper we have to save.

Answer :

Given:


Total 221 trees in forest


17 trees require to make 1 tonne of paper


Formula Used\Theory:


Dividing total amount by amount of 1 item gives


Number of items


(i) (A) 5 tonnes of paper


17 trees require to make 1 tonne of paper


Then;


5 tonnes of paper require


17 × 5 trees


= 85trees


Fraction of forest =


Fraction of forest =


(B) 10 tonnes of paper


17 trees require to make 1 tonne of paper


Then;


10 tonnes of paper require


17 × 10 trees


= 170trees


Fraction of forest =


Fraction of forest =


(ii) To save part of forest


Means;


× 221 trees to be saved


= 7 × 17


= 119trees to be saved


If 17 trees require to make 1 tonne of paper


Then;


Number of tonnes of paper to be saved =


= 7 tonnes


7 tonnes of paper are require to save part of forest
