Final answer:
To find what percent 80 is of 400, divide 80 by 400 and multiply by 100, resulting in 80 being 20% of 400.
Step-by-step explanation:
To determine what percent 80 is of 400, we need to divide the amount (80) by the base (400) and then multiply the result by 100 to get the percentage. Therefore, the calculation is (80 ÷ 400) × 100 = 20%. In this problem:
- The amount is 80.
- The base is 400.
- The rate (or percent) is the unknown we are trying to find.
After performing the calculation, we can conclude that 80 is 20% of 400.
