Pre-assessments change over time, so some of these short answers and explanations may not
match the questions on your Pre-assessment Coaching Report.
If you notice any differences, email us to let us know at so we can update
these explanations.
1. +/- 5.0: 25 is the only whole number. The square roots of 25 are ±5.
2. 15: 10 and 5 are the only whole numbers, and 10 + 5 = 15.
3. 67: Use PEMDAS-> 4 + 7 × 3^2 = 4 + 7 × 9 = 4 + 63 = 67
4. 49: Use PEMDAS-> 5 × 3^2 + 4 = 5 × 9 + 4 = 45 + 4 = 49
5. 11: The square root of 121 is 11, and 11 is the largest number that divides
evenly into both 132 and 11.
6. 12: 12 is the largest number that divides evenly into both 24 and 84.
7. 1/14: Use common denominators-> 3/14 − 1/7 = 3/14 −
2/14 = 1/14 8. 11/12: Use common denominators-> ⅔ + ¼ =
8/12 + 3/12 = 11/12
9. 46.8: The unrounded sum is 46.83, which rounds to nearest tenth as 46.8.
10.0.037: The unrounded answer is 0.03675, which rounds to the nearest thousandth
as 0.037.
11.270 mL: 4.5mL/min × 60min/hr = 270mL/hr (note the min’s cancel)
amt increase as a percent amt increase in mg x 40
12. 22.2%: , solve
use
original amt as a percent = original amt in mg , 100 = 180
with butterfly method
13. 77: The formula is F = 9/5 × C + 32. So, F = 9/5 × 25 + 32 = 77.
14. 38.9: The formula is C = 5/9 × (F - 32). So, C = 5/9 × (102 - 32) = 38.8888…,
