Question
Rama has `6 1/4` kg of cotton wool for making pillows. If one pillow takes `1 1/4` kg, how many pillows can she make?
Solution
Given, Rama has `6 1/4` kg of cotton for making pillows
i.e. `6 1/4` kg = `((6 xx 4) + 1)/4`
= `(24 + 1)/4`
= `25/4` kg
Where one pillow can be made from `1 1/4` kg
i.e. `1 1/4` kg = `((1 xx 4) + 1)/4`
= `(4 + 1)/4`
= `5/4` kg
∴ Number of pillows = `"Total quantity of cotton available"/"Cotton used in one pillow"`
= `((25/4))/((5/4))`
= `25/4 xx 4/5`
= `25/5` ......[∵ Division is reverse of the multiplication]
= 5
Hence, Rama can make 5 pillows.
