Understanding Ratios

The video tutorial introduces the concept of ratios as a comparison of two numbers and explains how they can be written in three different ways: using the word 'to', a colon, or as a fraction. It emphasizes the importance of simplifying ratios and maintaining the order of items being compared. The tutorial provides examples, including fish caught by Adam and Andrew, students to teachers, and shapes like triangles and circles. The video concludes with a reminder that Mumu Math uploads new math videos daily.

What is a ratio?

• A mathematical operation

• A comparison of three numbers

• A type of fraction

• A comparison of two numbers

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

• Using a fraction

• Using a semicolon

• Using a colon

• Using the word 'to'

If Adam caught 2 fish and Andrew caught 6, what is the simplified ratio of Adam's catch to Andrew's?

• 1 to 3

• 2 to 6

• 3 to 1

• 6 to 2

How should ratios be treated in terms of fractions?

• They should be simplified

• They should be multiplied by 10

• They should be converted to mixed numbers

• They should be left as improper fractions

What is the ratio of the total number of fish caught to the number caught by Andrew?

• 8 to 6

• 3 to 4

• 4 to 3

• 6 to 8

For 24 students and 1 teacher, what is the ratio of students to teachers?

• 1 to 24

• 24 to 1

• 12 to 1

• 1 to 12

If there are 2 triangles and 4 circles, what is the simplified ratio of triangles to circles?

• 2 to 1

• 4 to 2

• 2 to 4

• 1 to 2

What is the ratio of circles to the total number of shapes if there are 4 circles and 6 total shapes?

• 6 to 4

• 3 to 2

• 2 to 3

• 4 to 6

Why is it important to maintain the order when writing ratios?

• Because it is a rule of fractions

• Because it changes the meaning of the comparison

• Because it affects the mathematical operation

• Because it is easier to calculate

What should you do if you encounter a ratio that can be reduced?

• Multiply it by 2

• Simplify it

• Leave it as it is

• Convert it to a mixed number
