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

Respuesta :

Answer:

10

Step-by-step explanation:

[tex]45*\frac{1}{3} *\frac{2}{3} =45*\frac{2}{9} =10[/tex]

2/3 of the houses sold is equivalent to 1/3 of the houses remaining, so multiply the original number by 1/3 and 2/3 (since 1/3 of the remaining sold this month) to get the # of remaining houses.
