Final answer:
Circled primes, crossed composites in the list from 1 to 100.
Step-by-step explanation:
The prime numbers in the list from 1 to 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97. We can circle these numbers. The composite numbers are the non-prime numbers, so all numbers in the list that are not prime should be crossed. The circled numbers are prime, while the crossed numbers are composite.
