Question

is each number prime or composite? prime composite 5 ○ ○ 9 ○ ○ 57 ○ ○

Explanation:

Step1: Analyze 5

A prime number has only 1 and itself as factors. The factors of 5 are \(1\) and \(5\), so it is prime.

Step2: Analyze 9

A composite number has more than two factors. The factors of 9 are \(1\), \(3\), and \(9\) (\(9 = 3\times3\)), so it is composite.

Step3: Analyze 57

Find factors of 57: \(57 = 1\times57 = 3\times19\). It has factors \(1\), \(3\), \(19\), \(57\), so it is composite.

Answer:

For 5: Prime (circle the Prime option for 5)
For 9: Composite (circle the Composite option for 9)
For 57: Composite (circle the Composite option for 57)
