Answer 1

To find what percentage 4 students represent out of 20, divide 4 by 20 to obtain 0.20 and then multiply by 100 to get 20%. Hence, the correct answer is a) 20%.

Step-by-step explanation:

To calculate what percentage 4 students represent out of 20 students, you can set up an equivalent fraction and then convert that fraction to a percentage. If you have 4 students out of 20, your fraction would be ⅓/20. To convert this fraction to a percentage, you multiply by 100.

Here's the calculation step by step:

1. Write the fraction of 4 students out of 20: ⅓/20.
2. Divide 4 by 20 to get the decimal: 0.20.
3. Multiply the decimal by 100 to get the percentage: 0.20 × 100 = 20%.

Therefore, 4 students is 20% of 20 students, so the correct answer is a) 20%.
