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
