Answer:
she forgot to start with the equals sign.
Step-by-step explanation:
When you are entering a formula in Excel you have to start with the equals sign, so the program understands that it is a formula that is going to use the parameters you are going to indicate. If Ashley enters the formula and instead of the answer she sees b2 b3/c5, the mistake is that she didn't start with the equals sign that indicates that it is a formula to make a calculation using the cells entered.
