Answer:
1.4 or 30.8
Step-by-step explanation:
1.4 is for regular math because it's basically 16.1 - 14.7
30.8 is for KCO or Keep Change Opposite (Beginners math)
Basically it would turn the equation into 16.1 + 14.7
You can use either but if you aren't sure ask your teacher about the strategy.
Hope this helps and if not tell me your strategy.
