Question

It takes `2 1/3` m of cloth to make a shirt. How many shirts can Radhika make from a piece of cloth `9 1/3` m along?

Sum

Solution

Given, Radhika takes `2 1/3` m of cloth to make a shirt

i.e. `2 1/3` m = `((2 xx 3) + 1)/3`

= `(6 + 1)/3`

= `7/3` m

If Radhika has `9 1/3` m long cloth

i.e. `9 1/3` m = `((9 xx 3) + 1)/3`

= `(27 + 1)/3`

= `28/3` m

Then, number of shirts that can be made = `"Available cloth"/"Required cloth to make one shirt"`

= `(28/3)/(7/3)`

= `28/3 xx 3/7`  .......[∵ Division is reverse of the multiplication]

= `28/7`

= 4

Hence, Radhika can make 4 shirts from available piece of cloth.
