(1 point)
A. 62 kg
B. 75 kg
C. 84 kg
D. 92 kg
To solve this problem using a proportion, we can set up the following equation:
1 kg / 2.2 lbs = x kg / 185 lbs
Cross-multiplying, we get:
2.2 lbs * x kg = 1 kg * 185 lbs
Simplifying, we get:
2.2x = 185
Dividing both sides by 2.2, we get:
x = 185 / 2.2
x ≈ 84
So, 185 pounds is approximately equal to 84 kilograms.
Therefore, the correct answer is C. 84 kg.
