Round calculations to 2 decimal places

Type of calculation: Finding the portion of a total number based on a percentage.
How to use the calculator:
Step 1 (Your share): Use the Basic Percentage CALCULATOR ("What is X% of Y?"). Enter your share as 60 [X] and the total bill as 250 [Y]. It will show you 60% of 250.
Step 2 (Roommate's share): Do the same thing for your roommate. Enter their share as 40 [X] and the total bill as 250 [Y]. It will show you 40% of 250.
The formula:
We need to find 60% and 40% of 250.
Your share = (60 / 100) × $250 = 0.6 × $250 = $150
Roommate's share = (40 / 100) × $250 = 0.4 × $250 = $100
