Abuilder planned to build houses. each house will be built on 5/6 of an acre. how much land would be needed for 7 houses? the builder began with 10 acres of land . after 7 houses were built, how much land was left unused?

acres of land would be needed for 7 houses.

acres of land was left unused.

Step-by-step explanation:

We have been given that each house will be built on 5/6 of an acre.

To find the area it will take to build 7 houses, we will multiply area need to build one house by 7 as:

Therefore, acres of land would be needed for 7 houses.

Since builder began with 10 acres of land, so we can find the unused land by subtracting  from 10 as:

Therefore, acres of land was left unused.
