[tex]\frac{(new) - (original)}{original} = \frac{\frac{3}{8}- \frac{5}{4} }{\frac{5}{4} }[/tex]
[tex]\frac{3}{8} - \frac{5}{4} (\frac{2}{2}) = \frac{3}{8} - \frac{10}{8} = \frac{-7}{8}[/tex]
[tex]\frac{-7}{8}[/tex] ÷ [tex]\frac{5}{4}[/tex]
= [tex]\frac{-7}{8}[/tex] * [tex]\frac{4}{5}[/tex]
= [tex]\frac{-7(4)}{8(5)}[/tex]
= [tex]\frac{-7}{2(5)}[/tex]
= [tex]\frac{-7}{10}[/tex]
= -0.70
