Question

Sally needs 6 gallons of water, but she only has a 2 quart pitcher. how many times does she need to fill it up to make 6 gallons?

Answer 1

2 quart pitcher times 2 trips to get 1 gallons of water. Multiply that by 6.

12 trips in total

Answer 2

12 times

Explanation:

This is a unit conversion problem. In order to solve it we need the equivalence between this two measurement units. Which is:

`1Galllon=4Quarts`

This equivalence can be used as a conversion factor like this:

`(4Quarts)/(1Gallon)`

Applying it to the problem we can convert from gallons to quarts:

`6Gallons*(x4Quarts)/(1Gallon)=24Gallons`

Now we know that we have to fill up 24 gallons of water and as we will do it with a 2 quarts pitcher we will dive it by 2 to know how many times we need to fill up this pitcher:

`(24)/(2)=12`

She needs to fill the 2 quart pitcher 12 times to make 6 gallons
