There are 90 new houses being built in a neighborhood last month 1/6 of them were sold this month 1/3 of the remaining houses were sold. How many houses are left to be sold?

Answer: 50 houses are left to be sold.

Step-by-step explanation:

The total number of new houses that were built in the neighborhood last month is 90.

1/6 of them were sold this month. This means that the number of houses that were sold this month is

1/6 * 90 = 15

The number of houses remaining would be

90 - 15 = 75

1/3 of the remaining houses were sold. This means that the number of houses that were sold is is

1/3 * 75 = 25

Therefore, the number of houses that are left to be sold is

75 - 25 = 50
