Yes they are equivalent because 4 (weeks) x 7 (days in a week) = 28 days. 14 days is 2 weeks, 2 weeks times another 2 weeks is 4 weeks. In order to keep it equal times 12 by 2, making it 24. Making both be 24/28, meaning it's equal. Does that make sense?

They are not equivalent because if you do 12 x 2 it is 24, but 4 x 2 is not 14
