77.8dm converted to hm

77.8 \, \text{dm} = ? \, \text{hm}

To convert decimeters (dm) to hectometers (hm), we need to recall the metric system conversions. We know that:

1 \, \text{hm} = 10,000 \, \text{dm}

So, to convert 77.8 dm to hm:

77.8 \, \text{dm} = \frac{77.8}{10,000} \, \text{hm}

Now let's perform the calculation:

77.8 \div 10,000 = 0.00778 \, \text{hm}

Thus, the conversion result is:

[-Solution-]

0.00778 \, \text{hm}

[-Step-by-Step-]

1. Recall the conversion factor: 1 \, \text{hm} = 10,000 \, \text{dm}
2. Use the conversion factor to set up the equation: 77.8 \, \text{dm} = \frac{77.8}{10,000} \, \text{hm}
3. Perform the division: 77.8 \, dm \div 10,000 = 0.00778 \, hm
4. Final answer: 0.00778 \, \text{hm}
