Step-by-step explanation:
A: false. since there are 10 girls in mrs. bovine's class, and the number that they are asking is an odd number, it is impossible to say true. the same with the boys, since there are 18 boys and 18 is an even number and what they are asking is also an odd number.
B: true. if we add all the total students together, the total is 26 students. the ratio is a simplified one, and 26 is also the second multiple of 13. there are 14 boys in the class, and 14 is <em>also</em> the second multiple of 7!
C: false. although 10 is the fifth multiple of 2, 15 is the <em>third</em> multiple of five. alas, this problem is not correct.
D. false. 16 is not a multiple of 3, but 28 is a multiple of 7.
