Answer: a) 16 gallons b) 32 gallons
Explanation:
Since we have given that
Number of gallons = 12
Part of capacity filled =
![(3)/(4)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/3plulv07o1q6lxwcwi5q9gkjxxpacyi9ql.png)
So, the capacity of the tank is given by
![\frac{\text{Number of gallons}}{\text{Part of capacity of tank}}\\\\\\=(12)/((3)/(4))\\\\=(12* 4)/(3)\\\\=4* 4\\\\=16\ gallons](https://img.qammunity.org/2019/formulas/mathematics/middle-school/afo3hfwhrq1zrpr9v7ks13jlcsaklibbvw.png)
a) the capacity of tank = 16 gallons
b) If the tank is then filled to the capacity, how many half gallon bottles can be filled in the water tank?
Number of half gallons bottles would be
![(16)/((1)/(2))\\\\\\=16* 2\\\\=32\ gallons](https://img.qammunity.org/2019/formulas/mathematics/middle-school/cchkf4l7ksnhp3vk3u40pi22tyimare6ef.png)
Hence, a) 16 gallons b) 32 gallons
