Answer 1

The proportion 1 L : 0.26 gal = x L : 12500 gal.

Explanation:

Given:

A fountain holds 12,500 gallons of water.

1 L = 0.26 gal

Now, to get the proportion to solve for the number of litres.

`1\ L : 0.26\ gal = x\ L:12500\ gal`

`(1\ L)/(0.26\ gal) =(x\ L)/(12500\ gal)`

On solving :

`x=12500((1)/(0.26))\ L`

Therefore, the proportion 1 L : 0.26 gal = x L : 12500 gal.
