Question

Identify the percent of change as an increase or a decrease. 3/8 to 7/8. Find the percent of change. Round to the nearest tenth of a percent if necessary.

Answer 1

Answer:

Percentage of change is increase .

The percentage of change is  133.3 % (Approx).

Step-by-step explanation:

Formula

$Percentange = \frac{Change\ in\ value\times 100}{Initial\ value}$

As given

$The\ fraction\ changes\ from\ \frac{3}{8}\ to\ \frac{7}{8} .$

Clearly the fraction is increase .

$Change\ in\ value = Final\ value - Initial\ value$

Here

$Initial\ value = \frac{3}{8}$

$Final\ value = \frac{7}{8}$

Put in the formula

$Change\ in\ value = \frac{7}{8} - \frac{3}{8}$

$Change\ in\ value = \frac{7 - 3}{8}$

$Change\ in\ value = \frac{4}{8}$

Put in the formula

$Percentange = \frac{\frac{4\times 100}{8}}{\frac{3}{8}}$

$Percentange =\frac{400}{3}$

Perecntange = 133.3 % (Approx)
