Answer:

.20

Step-by-step explanation:

The word percent literally means "Out of 100". With that being said, 20% can be written as a fraction, mixed number or whole number as follows: 1/5 (fraction), 20/100 (mixed number) or .20 (whole number).

Answer:

1329 students

Step-by-step explanation:

20/100 ×6645

Reduce the fraction 20/100 with 20

So..20 goes into 20 1 time and 20 into 100 5 times

1/5×6645

Use 5 as the greatest common factor now

so...5 into 5 goes 1 time and 5 into 6645 goes 1329

1/1 × 1329 = 1329

Or... you could just convert 20% into a decimal by carring the . two places to the left

which is 0.2

0.2 × 6645 = 1329
