Percent Increase and Change Problems

The video tutorial explains how to calculate percent increase by using two examples. The first example demonstrates the increase from 5 to 8, resulting in a 60% increase. The second example shows the increase from 20 to 30 students, resulting in a 50% increase. The process involves finding the change, dividing by the original number, converting to a decimal, and then to a percentage.

What is the first step in finding the percent increase?

• Multiply the numbers together.

• Divide the larger number by the smaller number.

• Calculate the difference between the two numbers.

• Identify the larger number as the original.

In problem 1, what is the change when the number goes from 5 to 8?

• 4

• 5

• 3

• 2

How do you convert a decimal to a percentage?

• Multiply by 10

• Divide by 10

• Move the decimal point two places to the left

• Move the decimal point two places to the right

What is the percent increase from 5 to 8?

• 50%

• 80%

• 60%

• 70%

In problem 2, what is the original number of students?

• 10

• 20

• 40

• 30

What is the change in the number of students from 20 to 30?

• 20

• 15

• 10

• 5

What is the decimal representation of the change from 20 to 30?

• 0.3

• 0.6

• 0.4

• 0.5

What is the percent increase from 20 to 30?

• 40%

• 60%
