If a group of friends wants to divide a bill of $120 equally, they would each need to contribute an equal amount. To calculate this, we divide the total bill amount by the number of friends in the group.
If there are n friends in the group, each person would need to pay $120 divided by n. For example, if there are 6 friends, each person would pay $120 ÷ 6 = $20.
Dividing the bill equally ensures that each person contributes their fair share, making it a straightforward and equitable way to split expenses among friends.
