Final answer:
When combining a 5/8 acre parcel with a 3.9 acre parcel, the total size of the parcel will be 4.525 acres when expressed as a decimal.
Step-by-step explanation:
When an investor seeks to combine a 5/8 acre parcel with a 3.9 acre parcel, the process involves adding the two areas together to determine the total size of the combined parcels expressed as a decimal. Converting 5/8 to its decimal form yields 0.625. The calculation then entails adding this decimal representation of 5/8 acre to the area of the 3.9 acre parcel.
Expressed in mathematical terms, the calculation is as follows:
\[ 0.625 \, \text{(5/8 acre converted to decimal)} + 3.9 \, \text{(3.9 acre parcel)} = 4.525 \, \text{acres}.\]
Therefore, the combined parcel, comprising the 5/8 acre and the 3.9 acre portions, would have a total area of 4.525 acres.
This calculation is fundamental in real estate or land investment scenarios where investors may acquire or consolidate multiple parcels of land. Understanding the total acreage of combined parcels is essential for various purposes, including zoning considerations, development potential, and overall assessment of the property's value. In this case, the investor would now have a clear understanding that the combined area of the two parcels is 4.525 acres, providing valuable information for further investment analysis and decision-making.
