A swimming pool holds 15,000 gallons of water. If 1 cubic foot equals approximately 7.48 gallons, which value is closest to the pool's…

Each cubic foot holds about $7.48$ gallons, so the number of cubic feet is the number of gallons divided by $7.48$: $\frac{15{,}000}{7.48}\approx2005$, choice G. A check by estimation: $15{,}000\div7.5=2000$. Choice J ($112{,}200$) multiplies by $7.48$, which would convert in the wrong direction. Choice H ($15{,}000$) uses the gallons themselves, without conversion. Choice F ($1{,}000$) divides by about $15$. Since each cubic foot holds more than one gallon, the volume in cubic feet must be less than the volume in gallons.
