Question 834022
ratio problem, when the bucket is full it will hold 5 out 5 or 5/5 which is 1 (as in 1 whole bucket. So x liters when the bucket is full. 
56---4/5
x----1
Multiply across and you get
{{{4x/5=56*1}}} now solve for x
{{{4x/5=56}}} multiply each side by 5/4 so that you get x by itself
{{{x=56*(5/4)}}}
{{{x=70}}} liters
