12. A student claims that 2 is the only even prime number. Is the student's claim correct?
Yes, the student's claim is correct. A prime number has only two factors: 1 and itself. Every even number greater than 2 is divisible by 2 (in addition to 1 and itself), so they all have at least three factors and cannot be prime.
10. A students is asked to compare 3/8 and 5/12. They claim it's too hard because the denominators are different.
What is one strategy they could use to correctly compare the two fractions?
one strategy is to find a common denominator. A common multiple of 8 and 12. 3/8 is equivalent to 9/24 and 5/12 is equivalent to 10/24. Now it is easy to see that, 10/24 is greater than 9/24.

d. 7,9,13,15
b. 4,6,8,9
