Convert 387¼ kg to Tonnes: Mixed Number Unit Conversion

To solve this problem, we'll follow these steps:

• Step 1: Convert the mixed number into a decimal.
• Step 2: Use the correct conversion factor to translate kilograms into metric tons.

Let's begin the conversion:

Step 1: Convert the given weight $387\frac{1}{4}$ kilograms into a decimal.
To convert $387\frac{1}{4}$, decode the mixed number: $\frac{1}{4} = 0.25$, so $387\frac{1}{4} = 387 + 0.25 = 387.25$ kg.

Step 2: Use the conversion factor $1 \text{ metric ton} = 1000 \text{ kg}$ to convert kilograms into metric tons.
Calculate by dividing the kilograms by 1000:
$387.25 \text{ kg} \div 1000 = 0.38725 \text{ metric tons}.$

Therefore, the weight of $387\frac{1}{4}$ kg is equivalent to $0.38725$ metric tons.
