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 1

Fraction = 25/50 = 1/2

Jamaal = No. of pencils he had iAnswer:

yes

Step-by-step explanation:

Ramesh = No. of pencils he had in 1st month = 20 pencils

              = No. of pencils he had at the end of 4th month = 10 pencils

Fraction = 10/20 = 1/2

Sheelu = No. of pencils she had in 1st month = 50 pencils

            = No. of pencils she had at the end of 4th month = 25 pencils

Fraction = 25/50 = 1/2

Jamaal = No. of pencils he had in 1st month = 80 pencils

            = No. of pencils he had at the end of 4th month = 40 pencils

Fraction = 40/80 = 1/2

Therefore, yes, each of the kids have used up equal fraction of pencils.

Answer 2

Answer:

Step-by-step explanation:

Ramesh: Total pencil=20 used pencil=10 fraction used=10/20=1/2

Sheelu: Total pencil=50 used pencil=25 fraction used=25/50=1/2
