What you’ll learn
Find a percent of a quantity.
Key idea
Percent of a whole means multiplying by the fraction with denominator one hundred.
The percent denominator must remain in multiplication; a single segment is not the final multi-segment part.
Worked example
Enter the exact value or ordered values in the format requested below.
Find 5% of 340 beads. Include the unit beads.
- The percent rate is 5/100=1/20.
- Multiplying the whole 340 by that fraction gives 17 beads.
