Understanding Ratios and Their Simplification

The video tutorial explains the concept of ratios, how to write them, and the importance of reducing them to their simplest form. It covers equivalent ratios and demonstrates how to simplify ratios using common factors, similar to reducing fractions. The tutorial emphasizes the need to express ratios in their simplest form for clarity and accuracy.

What is a ratio?

• A comparison between two or more related quantities

• A comparison between two or more unrelated quantities

• A type of fraction

• A mathematical operation

Which of the following is NOT a way to write a ratio?

• Using a colon

• Using a semicolon

• As a fraction

• Using the word 'to'

If there are 8 boys and 12 girls in a room, what is the simplified ratio of boys to girls?

• 1 to 2

• 2 to 3

• 4 to 6

• 8 to 12

In the cookie example, what is the initial ratio of cookie pieces to frosting pieces?

• 4 to 2

• 8 to 4

• 6 to 3

• 2 to 1

How can the ratio 8 to 4 be simplified directly to 2 to 1?

• By dividing both numbers by 2

• By adding 2 to both numbers

• By dividing both numbers by 4

• By multiplying both numbers by 2

What is the key idea to remember when reducing ratios?

• Ratios should always be expressed as whole numbers

• Ratios can be reduced using the same logic as reducing fractions

• Ratios are always expressed in decimal form

• Ratios can be increased using the same logic as increasing fractions

Which of the following is an equivalent ratio to 4 to 2?

• 8 to 4

• 6 to 4

• 3 to 1

• 5 to 3

Why is it important to express ratios in their simplest form?

• To increase their value

• To make them more complex

• To make them easier to compare

• To convert them into fractions

• 4 to 2

• 1 to 2

• 8 to 4

• 2 to 1

What is the main lesson learned about ratios in this video?

• Ratios should be expressed in decimal form

• Ratios can have smaller equivalent ratios

• Ratios are always expressed as whole numbers

• Ratios should be increased to their largest form
