(2). Looking at the denominators, only option 2 has a numerator that is less than half its denominator.

Here is a hint: Make the numerator of 1/2 to be the same for each of the options. For example, (1) 2/3 vs 2/4 (2) 3/7 vs 3/6 (3) 3/5 vs 3/6 (4) 5/9 vs 5/10 Now, compare the denominators. (1) 3 vs 4 (2) 7 vs 6 (3) 5 vs 6 (4) 9 vs 10 The one with the larger denominator wins. In this case, it is (2).

For P3, they should be taught to use half as a benchmark.

If you did what half is the denominator is and compare that to the numerator, it's pretty quick. 1) 2/3- half of 3 is 1.5 and 2 is more than that. So 2/3 is more than 1/2. 2) 3/7- half of 7 is 3.5 and 3 is less than that, so 3/7 is less than 1/2...

If the folded pieces were unfolded, each angle would be 13 x 2 = 26 degrees. So <CAD = 90 - 26 -26
