Answer:
12 houses
Explanation:
First you need to figure out how many were sold the first month. You need to figure out how much 1/3 of 48 is, so you need to divide 48 by 3, equaling 16. You then multiply 16 by two, because they didnt sell 1/3, but 2/3. 16 times 2 is 32, so 32 houses were sold in the first month, by doing 48-32, you can say that there were 16 houses left to sell. Then if 1/4 of those houses were sold the next month, then you need to figure out what 1/4 of 16 is. In the same way as before, you divide 16 by 4, which equals 4. If they sold 4 of 16 the next month, you then need to subtract 16 by 4, equaling 12. This means there are 12 houses remaining to be sold.
