Question

At a store, 2 gallons of milk cost $6. Which is the value of the ratio of dollars to gallons of milk?

Answer 1

1 gallon = $3 so the ratio would be 1:3 where 1 would represent the gallon and 3 the price

Answer 2

3:1 or 3/1

Explanation:

We have the next information:

Gallons of Milk Cost

2 ⇒ $6

dividing both quantities by two, we get the price for a single gallon of milk:

Gallons of Milk Cost

1 ⇒ $3

We are asked for the ratio of dollars to gallons of milk (the order is important since dollars go first than gallons) so we will have the following:

dollars:gallons or dollars/gallons

and since $3 dollars pay for 1 gallon of milk, the ratio is:

3:1 or 3/1
