Answer:

4 students is 20% of 20 students.

Step-by-step explanation:

We can say that 20 students represent 100% and that 4 students represent x% of all students. Then we can use the proportion: 20 : 4 = 100 : x, or 20 / 4 = 100 / x. Then we will cross multiply: 20 x = 4 * 100, 20 x = 400, x = 400 : 20 , x = 20 %. Also we can say that 4 = 1/5 * 20 and 1/5 * 100 = 20 %

Answer:

20%

Step-by-step explanation:

Let x be the percent.

  1. Write it out: 4 students is x% of 20
  2. Write as a proportion: [tex]\frac{4}{20} = \frac{x}{100}[/tex]  
  3. Cross multiply, then divide: 100 × 4 = 400, 400 ÷ 20 = 20
  4. So, 4 students is 20% of 20 students.

I hope this helps!
