Given:

Ramesh had 20 pencils, Sheelu had 50 pencils and Jamaal had 80 pencils. After 4 months, Ramesh used up 10 pencils, Sheelu used up 25 pencils and Jamaal used up 40 pencils.

.To do:

We have to find the fraction(of pencils) each used up.

Solution :

Total number of pencils Ramesh had $= 20$

Number of pencils used by Ramesh $= 10$

Fraction of pencils used up by Ramesh $= \frac{10}{20}$

$=\frac{1}{2}$

Total number of pencils Sheelu had $= 50$

Number of pencils used by Sheelu $= 25$

Fraction of pencils used up by Sheelu $= \frac{25}{50}$

$=\frac{1}{2}$

Total number of pencils Jamaal had $= 80$

Number of pencils used by Jamaal $= 40$

Fraction of pencils used up by Jamaal $= \frac{40}{80}$

$=\frac{1}{2}$

Therefore, each has used up an equal fraction($\frac{1}{2}$) of pencils.
