My working hours were reduced by %. If I previously worked hours a week...
How many hours will I work now?

Type of calculation: Calculating the value after a percentage decrease.
Calculator usage:
Step 1: Calculate by how many hours the working time was reduced. Use the Basic Percentage CALCULATOR ("What is X% of Y?"). Enter the reduction percentage as X (20) and the original number of hours as Y (40). The calculator will calculate 20% of 40 hours.
Step 2: Subtract the number of hours calculated in Step 1 from the original number of hours.
Explanation using a formula:
We are looking for the number of working hours after a 20% reduction from 40 hours.
Reduction in working time = 20% of 40 hours
Reduction in working time = (20 / 100) * 40 hours = 0.2 * 40 hours = 8 hours
New working hours = Original working hours - Reduction in working time
New working hours = 40 hours - 8 hours = 32 hours
