There are 45 new houses being built in a neighborhood. Last month 1/3 of them were sold. This month 2/5 of the remaining houses were sold. How many houses are left to be sold

Respuesta :

Answer:

18

Step-by-step explanation:

First we find out how much were sold last month:

1/3 x 45 = 15

Then we know that there are still 30 houses left to sell because 45 - 15 = 30

The houses that were sold this month:

2/5 x 30 = 12

Because we know that 12 more houses were sold, the remaining would be  30 - 12, which is 18
