Answer 2

Answer:

41 students

Step-by-step explanation:

We're trying to find what 20% of 205 is so:

We start by converting 20% to a fraction :

20% = 1/5

Then we have

20% of 205 = 1/5 x 205 = 1/5 x 205/1 = 205/5

Notice that 205 was rewritten as the fraction 205/1, and that to multiply two fractions together, you simply multiply the numerators and denominators.

In order to find the simplest form of 205/5 we cancel out the greatest common divisor of 205 and 5, which is 5:

205/5 = 41/1  

So there are 41 5th graders
