Calculation type: Finding the value after a percentage decrease.
Calculator usage: Step 1: Calculate the reduction hours. Use the
Basic Percentage CALCULATOR ("What is X% of Y?"). Enter
20 [X] and
40 [Y]. The calculator will determine
20% of
40 hours.
Step 2: Subtract the number of hours calculated in Step 1 from the original number of hours.
Formula explanation:
We want to find the 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
