GCSE maths question on successive percentages

Hello, I'm finding this question quite hard:

"Calculate the overall percentage change, stating whether it is an increase or a decrease. An 12% increase then a 12% decrease."
I understand that you would change then to their multipliers so 12% increase= x 1.12 and 12% decrease = x 0.88
Then you multiply the multipliers so 0.9856 but I'm really confused as to what you do next? Any help would be greatly appreciated!

1) Convert 0.9856 to percentage.

2) What is the difference between what you started with (that is, 100%) and your answer in 1)?

3) If your answer in 1) is less than 100% then it will be an overall decrease.

If your answer in 1) is more than 100% then it will be an overall increase.
