Simplifying Ratios and Proportions

The video tutorial explains the concept of proportion, where the ratio of the first two numbers is equal to the ratio of the last two numbers. It demonstrates how to check if two ratios are in proportion by simplifying them into fractions and verifying their equality. The example used involves simplifying the ratios 40:30 and 60:45 to 4:3, confirming they are in proportion.

What does it mean for two ratios to be in proportion?

• They have the same sum.

• They have the same difference.

• They are both greater than 1.

• They are equal when simplified.

How can you express a ratio in a different form?

• As a difference of numbers.

• As a product of numbers.

• As a fraction.

• As a sum of numbers.

What is the first step in checking if two ratios are in proportion?

• Subtract the ratios.

• Multiply the ratios.

• Add the ratios.

• Simplify the ratios.
