Answer:
The coefficient would be 2 and the operation would be subtraction.
Step-by-step explanation:
For the coefficient question, all you need to do is divide 4.86 by 2.43 (because the numbers are constants and when they are placed in a fraction model, they have to be divided).
For the last question, the operation would be subtraction because you subtracted 9 by 3 to get your correct answer of 6.
