Solving Percent Problems with Equivalent Ratios

The video tutorial explains how to solve percent problems using equivalent ratios. It covers examples involving school populations, band members, and shopping discounts. The tutorial demonstrates setting up ratios, identifying parts and totals, and calculating missing values to find solutions.

What is the first step in solving percent problems using equivalent ratios?

• Multiply the numerator and denominator

• Convert the percent to a fraction

• Identify the total amount

• Identify the part and the total

If 240 boys represent 20% of the total students, what is the total number of students?

• 1,200

• 1,500

• 1,000

• 2,000

What is the purpose of setting up equivalent ratios in percent problems?

• To find the missing part or total

• To convert percentages to decimals

• To simplify the problem

• To check the accuracy of the problem

How do you set up the ratio for 32% of students playing the flute?

• 32 out of 150

• 32 out of 200

• 32 out of 100

• 32 out of 50

If there are 200 students in the band and 32% play the flute, how many students play the flute?

• 66

• 64

• 60

• 62

What is the ratio for a 45% discount?

• 45 out of 200

• 45 out of 150

• 45 out of 100

• 45 out of 50

If the original price of a TV is $1,000 and the discount is 45%, what is the discount amount?

• $400

• $450

• $550

• $500

How do you calculate the sale price after a discount?

• Divide the discount by the original price

• Multiply the discount by the original price

• Add the discount to the original price

• Subtract the discount from the original price

What is the sale price of a TV originally priced at $1,000 with a $450 discount?

• $600

• $500

• $650

• $550

In the context of the video, what does the 'whole amount' refer to?

• The part of the total

• The total population or quantity

• The percentage value

• The missing value
