Question

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?

Answer

Ramesh \(=20\) pencils
Sheelu \(=50\) pencils
Jamaal \(=80\) pencils
After \(4\) months
Ramesh \(=10\) pencils used
Sheelu \(=25\) pencils used
Jamaal \(=40\) pencils used
Fraction of pencils used \(=\dfrac{10+25+40}{20+50+80}=\dfrac{75}{150}=\dfrac{1}{2}\)
Ramesh \(=\dfrac{10}{20}=\dfrac{1}{2}\)
Sheelu \(=\dfrac{25}{50}=\dfrac{1}{2}\)
Jamaal \(=\dfrac{40}{80}=\dfrac{1}{2}\)
Hence equal fraction of pencils all used.
