Answer: Percent of change is 70%.
Step-by-step explanation:
Since we have given that
[tex]\frac{5}{4}\ to\ \frac{3}{8}[/tex]
We need to find the percent of change.
So, First we find the difference between them:
[tex]\frac{5}{4}-\frac{3}{8}\\\\=\frac{10-3}{8}\\\\=\frac{7}{8}[/tex]
So, We know the formula for "Percent of change":
[tex]\frac{Difference}{Original}\times 100\\\\=\frac{\frac{7}{8}}{\frac{5}{4}}\times 100\\\\=\frac{7\times 4}{8\times 5}\times 100\\\\=70\%[/tex]
Hence, Percent of change is 70%.
