Finding Equivalent Ratios Methods

The video tutorial explains how to find equivalent ratios using two methods: multiplication and division. Multiplication is highlighted as the easier method, allowing for an infinite number of equivalent ratios by multiplying both parts of the ratio by the same number. Division is used for simplifying larger ratios by dividing both parts by a common factor, though it offers a limited number of solutions. The tutorial concludes by encouraging viewers to practice finding equivalent ratios.

What are the two methods mentioned for finding equivalent ratios?

• Addition and subtraction

• Multiplication and division

• Integration and differentiation

• Exponentiation and root extraction

When using multiplication to find equivalent ratios, what must be done to both parts of the ratio?

• Subtract the same number

• Multiply by the same number

• Add the same number

• Divide by the same number

If you start with the ratio 4:5 and multiply both numbers by 3, what is the new equivalent ratio?

• 8:10

• 16:20

• 20:25

• 12:15

What is a key difference between using multiplication and division to find equivalent ratios?

• Multiplication has a limited number of solutions

• Division has an infinite number of solutions

• Both methods provide infinite solutions

• Multiplication provides infinite solutions, while division is limited

When using division to find equivalent ratios, what must you identify first?

• The product of the numbers

• The sum of the numbers

• The difference between the numbers

• A common factor of both numbers

If you have the ratio 40:28, what is an equivalent ratio after dividing both numbers by 2?

• 20:14

• 4:3

• 10:7

• 8:5

Which method is more suitable for finding a large number of equivalent ratios quickly?

• Subtraction

• Division

• Multiplication

• Addition

What is the main concept behind finding equivalent ratios?

• Changing one part of the ratio

• Subtracting the same number from both parts

• Adding the same number to both parts

• Multiplying or dividing both parts by the same number

What is the result of dividing the ratio 40:28 by their greatest common factor?

• 20:14

• 10:7

• 5:3.5

• 2:1.4

What is the final message given to students at the end of the lesson?

• Division is the best method

• Always use multiplication

• Go have some fun with math

• Practice makes perfect
