Question

If a crate contains 25,500 ounces (oz) of rice, about how many kilograms (kg) does it contain?

(1 lb = 16 oz, 1 lb = 0.454 kg)
351 kg
724 kg
25,500 kg
185,000 kg

Answer 1

To convert ounces to kilograms, you can follow these steps:

1. Convert ounces to pounds.
2. Convert pounds to kilograms.

### Step 1: Convert ounces to pounds
We know that:
\[
1 \text{ lb} = 16 \text{ oz}
\]
Thus, to find the weight in pounds:
\[
\text{Weight in lb} = \frac{\text{Weight in oz}}{16} = \frac{25,500 \text{ oz}}{16} = 1,593.75 \text{ lb}
\]

### Step 2: Convert pounds to kilograms
We know that:
\[
1 \text{ lb} = 0.454 \text{ kg}
\]
Thus, to find the weight in kilograms:
\[
\text{Weight in kg} = \text{Weight in lb} \times 0.454 = 1,593.75 \text{ lb} \times 0.454 \text{ kg/lb} \approx 724.3 \text{ kg}
\]

Therefore, the crate contains about **724 kg** of rice.

The answer is **724 kg**.
