Question

There were 420 students participating in the Swachh Bharat campaign. They cleaned ${\displaystyle \frac{42}{75}}$ part of the town, Sevagram. What part of Sevagram did each student clean if the work was equally shared by all?

Answer 1

420 students cleaned ${\displaystyle \frac{42}{75}}$ part of the Sevagram town.

1 student cleaned the part of the Sevagram town equal to ${\displaystyle \frac{42}{75}÷420}$

= ${\displaystyle \frac{42}{75}\times \frac{1}{420}}$

= ${\displaystyle \frac{42}{75\times 420}}$

= ${\displaystyle \frac{1}{75\times 10}}$

= ${\displaystyle \frac{1}{750}}$

Hence, each student cleaned ${\displaystyle \frac{1}{750}}$ part of the Sevagram town.
