Answer: 22 houses.


Step-by-step explanation:

[tex]70houses*\frac{2}{5}=28houses[/tex]

2. You can calculate the number of the remaining houses sold this month as following:

[tex]28houses*\frac{5}{7}=20houses[/tex]

3. Then, the number of houses are left to be sold is:

[tex]70houses-28houses-20houses=22houses[/tex]
