Understanding Ratios

The video tutorial from Moomoomath and Science explains how to write ratios in three different ways: as a fraction, using a colon, and in the form 'a to b'. It provides a step-by-step guide to identifying relationships, writing quantities in fraction form, and simplifying them. Three examples are used to illustrate the process: red boxes to blue boxes, dogs to cows, and ounces of oil to gallons of gas. Each example demonstrates how to simplify the ratio and express it in different forms. The video concludes with a reminder to be kind.

What is the first step in writing ratios in different forms?

• Simplify the fraction

• Write as a fraction

• Use a colon

• Identify the relationship

How can the ratio 9 red boxes to 3 blue boxes be simplified?

• 9:3

• 3:1

• 3:9

• 1:3

Which of the following is a correct way to express the ratio of 3 red boxes to 1 blue box?

• 1:1

• 3 to 1

• 1 to 3

• 3:3

What is the simplified form of the ratio 40 dogs to 6 cows?

• 20:6

• 20:3

• 40:6

• 10:3

If you have 20 dogs for every 3 cows, how can this ratio be written using a colon?

• 20:3

• 3:3

• 20:20

• 3:20

What is the first step in simplifying the ratio of 16 ounces of oil to 40 gallons of gas?

• Multiply by 4

• Multiply by 2

• Divide by 4

• Divide by 2

After simplifying, what is the ratio of 2 ounces of oil to 5 gallons of gas?

• 5:10

• 5:2

• 2:5

• 10:5

Which of the following is NOT a way to express the ratio 2 ounces to 5 gallons?

• 2:5

• 2 to 5

• 5:2

• 2/5

What is the final message conveyed in the video?

• Ratios are important

• Practice makes perfect

• Kindness multiplies kindness

• Always simplify ratios

What is the benefit of writing ratios in different forms?

• It is unnecessary

• It helps in better understanding

• It makes them more complex

• It changes the ratio
