Can be used to compare changes from one period to another.

vlada-n [284]

Answer:

c) Percentages

Step-by-step explanation:

Percentages can be used to compare changes from one period to another.

In calculating a percentage change, either a percentage increase or percentage decrease, we must have both the new and old measurement of the specific quantity.

For example, let's find percentage increase of the number of students that joined a book club using the parameters below;

Original number of students = 32

New number of students = 36

We will calculate the increase using;

$Increase = original \; number - new \; number$

Substituting the values, we have;

Increase = 36 - 32 = 4

$Percentage \; increase = \frac{increase}{original \; number} * 100$

$Percentage \; increase = \frac{4}{32} * 100$

$Percentage \; increase = 0.125 * 100$

Percentage increase = 12.5%

Therefore, the number of students in the school club increased by 12.5%.

Draw a division model to show how many 1/4 are in 3 1/2

Rina8888 [55]

First, you would need to create an equation for this problem.
3 $\frac{1}{2}$ ÷ $\frac{1}{4}$

Next, you would flip the second fraction and change it to multiplication.
3 $\frac{1}{2}$ × $\frac{4}{1}$

Now, you would change the first fraction into an improper fraction and cross simplify the equation.
$\frac{7}{2}$ × $\frac{4}{1}$
$\frac{7}{1}$ × $\frac{2}{1}$

Finally, you would solve it.
$\frac{7}{1}$ × $\frac{2}{1}$ = $\frac{14}{1}$ = 14

3 $\frac{1}{2}$ ÷ $\frac{1}{4}$ = 14

I hope this helps!
