Answer 1

True:
- Jayden's solution is incorrect. (14 ÷ (2 + 1.5) = 14 ÷ 3.5 = 4, not 8.5.)
- Jayden divided 14 by 2 and then added 1.5. (14 ÷ 2 = 7; 7 + 1.5 = 8.5.)

False:
- Jayden added inside the parentheses before dividing. (If he had, he would get 4.)
- Jayden substituted the wrong value for a. (a = 14 was used.)
- Jayden added inside the parentheses before multiplying. (There is no multiplication.)
