Answer:
20%
Step-by-step explanation:
Step 1: Find the decrease in consumption
10kg - 8kg = 2kg
So the family decrease their consumption of sugar by 2kg
Step 2: We have to find what percent did the family reduce their sugar consumption
We can divide how much they reduced by with the original amount
2kg/10kg = 1/5 kg or 20%
Therefore the family reduced the consumption of sugar by 20$
