Answer:

Mrs. Haley had  [tex]\mathbf{\frac{3}{14}}[/tex] liters of salt water left.

Step-by-step explanation:

Mrs Haley has salt = [tex]\frac{5}{7}\:liter[/tex]

Mrs Haley used salt = [tex]\frac{1}{2}\:liter[/tex]

We need to find how much salt is left?

[tex]Salt\: left = Total\: Salt - Salt\: used\\Salt\: left = \frac{5}{7}-\frac{1}{2}\\Salt\: left =\frac{5*2-1*7}{14} \\Salt\: left =\frac{10-7}{14} \\Salt\: left =\frac{3}{14}[/tex]

So, Mrs. Haley had  [tex]\mathbf{\frac{3}{14}}[/tex] liters of salt water left.
