Answer:
Percentage of change is increase .
The percentage of change is 133.3 % (Approx).
Step-by-step explanation:
Formula
[tex]Percentange = \frac{Change\ in\ value\times 100}{Initial\ value}[/tex]
As given
[tex]The\ fraction\ changes\ from\ \frac{3}{8}\ to\ \frac{7}{8} .[/tex]
Clearly the fraction is increase .
[tex]Change\ in\ value = Final\ value - Initial\ value[/tex]
Here
[tex]Initial\ value = \frac{3}{8}[/tex]
[tex]Final\ value = \frac{7}{8}[/tex]
Put in the formula
[tex]Change\ in\ value = \frac{7}{8} - \frac{3}{8}[/tex]
[tex]Change\ in\ value = \frac{7 - 3}{8}[/tex]
[tex]Change\ in\ value = \frac{4}{8}[/tex]
Put in the formula
[tex]Percentange = \frac{\frac{4\times 100}{8}}{\frac{3}{8}}[/tex]
[tex]Percentange =\frac{400}{3}[/tex]
Perecntange = 133.3 % (Approx)
