Emma has already read 6 of 20 books on her summer reading list. what percent of the books on her list has she read already?

To find the percent of the books she has read, divide the number that she has already read by the total number of books on her list.
Read: 6
Total: 20
6/20= 0.3
When you convert decimals to percentages, you move the decimal 2 spots to the right.  So 0.3= 30%
Therefore, Emma has read 30% of the books on her list :)

What are the options

31 is prime. and it’s prime factorization is just 31.
