Answer 1

lily has 13 yards of clothes

the total clothes length used by lily is

$=2\frac{6}{4}+3\frac{1}{3}+4.5$$\begin{gathered} =\frac{14}{4}+\frac{10}{3}+\frac{45}{10} \\ =\frac{14}{4}+\frac{10}{3}+\frac{9}{2} \end{gathered}$

so remaining yards is

$=13-(\frac{14}{4}+\frac{10}{3}+\frac{9}{2})$$\begin{gathered} =13-(\frac{42+40+54}{12}) \\ =13-\frac{136}{12} \end{gathered}$$=\frac{156-136}{12}=\frac{20}{12}=\frac{5}{3}$
