Final answer:
After consuming 9/10 kg of apples from an initial 2 1/5 kg, you will have 1 3/10 kg of apples remaining. The correct answer is option C, 1 3/10 kg.
Step-by-step explanation:
The subject of this question is Mathematics, specifically dealing with subtraction and fractions. We're given an initial quantity of apples which is 2 1/5 kg, and we know that 9/10 kg of apples are eaten. To find out how many kilograms of apples will be left, we perform the subtraction: 2 1/5 kg - 9/10 kg.
Firstly, convert 2 1/5 to an improper fraction which is 11/5. Then convert 9/10 to a fraction with the same denominator as 11/5, which in this case would be 18/10 (since 1 kg = 10/10 kg).
Now subtract 18/10 from 11/5:
11/5 kg (or 22/10 kg) - 9/10 kg = 13/10 kg or 1 3/10 kg
Therefore, after eating 9/10 kg of apples, you would be left with 1 3/10 kilograms of apples, which corresponds to answer choice C. 1 3/10 kg.
