Question: 8.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 is each has used up an equal fraction of her/his pencils?
Answer :
Ramesh: Total pencils = 20
Pencils used = 10
Fraction = 10⁄20 = 1⁄2
Sheelu: Total pencils = 50
Pencils used = 25
Fraction = 25⁄05 = 1⁄2
Jamaal: Total pencils = 80
Pencils used = 40
Fraction = 40⁄80 = 1⁄2
Since, all of them used half of their pencils, therefore each one used up equal fraction of pencils.
