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. What fraction did each use up? Check if each has used up an equal fraction of her/his pencils?
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.
