To find the answer of this question, you would take 4 acres and divide it by 2/3. This is because the development is 4 acres and is being divided into a certain number (that we are going to find) of 2/3 acre lots.
So by dividing the area of the neighborhood development lot (4 acres) by 2/3, you would find the total number of 2/3 acre lots that are going to be created.
4 acres / 2/3 acre lots
To divide fractions, you would multiply the fraction by its reciprocal. So your new expression, instead of 4 ÷ 2/3, would be 4 × 3/2.
Multiply straight across.
4 × 3/2 = 12/2 = 6
6 neighborhood development lots can be created by dividing the 4 acre lot into 2/3 acre lots.
