Change the fractions to decimals for as easy algebraic solution.
.5 - (.2 + .25) = .05. Only 1/10 of the clay is left.
.5 - (.2 + .25) = .05. Only 1/10 of the clay is left.
the first thing you want to do is make all of them have a common denominator
1/2 = 10/20
1/4 = 5/20
1/5 = 4/20
you then do 10/20 - 5/20 - 4/20
the final answer is 1/20 pounds of clay
1/2 = 10/20
1/4 = 5/20
1/5 = 4/20
you then do 10/20 - 5/20 - 4/20
the final answer is 1/20 pounds of clay
