To find 80% of 20, you can use a simple mathematical formula. Percentage means ‘per one hundred,’ so to calculate a percentage of a number, you multiply the number by the percentage (expressed as a decimal).
The formula is:
Result = (Percentage as a Decimal) × (Number)
In this case, 80% can be converted to a decimal by dividing by 100, which gives us 0.80. Now, apply the formula:
Result = 0.80 × 20
Calculating that gives:
Result = 16
So, 80% of 20 is 16.
This concept can be very useful in daily life, like when you’re figuring out discounts during sales or understanding how much of a total is allocated for a specific purpose.
