The increase will be D/4 (the amount they have to pay now) - D/5 (the amount to start with)

To take away fractions we can first make the denominators equal by multiplying the top and bottom by a number, in this case 4 and 5, then taking away the numerators away will give the answer, ie.

D/4 - D/5 = D*5/4*5 - D*4/5*4 = (5D-4D)/20 = D/20

So the cost to each person increased by D/20 dollars

Assume that ,the rent of the summer house is 200\$

5 friend wants to take the house for rent,so they have shared the rent in to five parts

so,each one has to pay 40\$ for month.each person has to pay 20% of the rent for every month

before one friend has dropped from the plan.

the four friend has to share the 40\$ rent between them,so each one has to pay more 10\$ for rent.it is equal to 5% of the total rent.

Each person will bear 25% of the rent
