Question

there are 60 new houses being built in a neighborhood. Last month, 2/3 of them were sold. This month, 2/5 of the remaining houses were sold. How many houses are left to be sold?

Answer 1

Sold Last Month: 60 x $\frac{2}{3}$ = 40

Remaining from last month: 60 - 40 = 20

Sold This Month: 20 x $\frac{2}{5}$ = 8

Remaining from this month: 20 - 8 = 12

Answer: there are 12 houses left to be sold
