To find out how much Katherin have left we need to substrac the amount she spent:

[tex]10-5\frac{1}{2}-2.6=10-5.5-2.6=1.9[/tex]

Therefore she has $1.9 left.

To do this same problem in fraction form we need to convert the 2.6 in fraction, to do this we multiply the number by 10 and divided by ten. Then:

[tex]2.6\cdot\frac{10}{10}=\frac{26}{10}=\frac{13}{5}[/tex]

then we have:

[tex]\begin{gathered} 10-5\frac{1}{2}-\frac{13}{5}=10-\frac{11}{2}-\frac{13}{5} \\ =\frac{100-55-26}{10} \\ =\frac{19}{10} \end{gathered}[/tex]

Therefore, the answer in decimal form is 19/10 dollars.
