Answer 1

625 gal, 187.5 gal, 80%

Explanation:

`(125)/(x)`=
`(20)/(100)` 125*100/20=625

`(x)/(625)=(30)/(100)` 30*625/100=187.5 or 625*.3=187.5

`(500)/(625)=(x)/(100)` 500*100/625=80

Answer 2

625

Explanation:

becuase 20% is equivilant to 1/5 you need to multiply by 5 to get 1t or full.

part b: 187.5

part c: 125 gallons is 25%. this is because you can fit 4 of it into one 500 gallon tank
