Exploring Ratio Word Problems

The video tutorial covers the concept of ratios, focusing on writing and finding equivalent ratios through word problems. It includes examples involving microscopes to students, books to students, and miles to minutes. The instructor emphasizes the importance of identifying the items being compared and maintaining consistent order when writing ratios. The tutorial also demonstrates how to find equivalent ratios by multiplying or dividing both terms of the ratio by the same number.

What are the two things being compared in the first example problem?

• Books and students

• Microscopes and students

• Miles and minutes

• Teachers and students

What is the ratio of microscopes to students in the first example?

• 4 to 10

• 4 to 20

• 1 to 5

• 2 to 20

How do you find an equivalent ratio for 4 microscopes to 20 students?

• Subtract 4 from both numbers

• Add 4 to both numbers

• Divide both numbers by 4

• Multiply both numbers by 2

If there are 8 microscopes, how many students would there be?

• 10

• 30

• 40

• 20

In the second example, what are the two things being compared?

• Teachers and students

• Miles and minutes

• Microscopes and students

• Books and students

What is the original ratio of books to students in the second example?

• 4 to 1

• 12 to 48

• 1 to 4

• 48 to 12

How many students are there if there are 48 books?

• 4

• 8

• 12

• 16

In the third example, what is the ratio of miles to minutes?

• 3 to 18

• 18 to 3

• 1 to 6

• 6 to 1

What is an equivalent ratio to 3 miles in 18 minutes?

• 1 to 6

• 6 to 1

• 6 to 3

• 3 to 6

What should you do first when solving a ratio problem?

• Write the numbers first

• Write the words first

• Divide the numbers

• Multiply the numbers
