Exploring Equivalent Ratios and Fractions

The video tutorial explains equivalent ratios, similar to equivalent fractions, and how to find them by multiplying or dividing the numerator and denominator by the same number. It includes examples and word problems to illustrate the concept, emphasizing the importance of maintaining the same multiplier or divisor for both parts of the ratio. The video concludes with a reminder of the key points and a message about kindness.

What can be done to find equivalent ratios?

• Add the same number to numerator and denominator

• Multiply the numerator and divide the denominator by the same number

• Multiply or divide the numerator and denominator by the same number

• Subtract the same number from numerator and denominator

What results from multiplying both the numerator and the denominator of a ratio by 2?

• The ratio becomes zero

• The ratio doubles

• The ratio is halved

What happens if you divide both the numerator and the denominator of a ratio by the same number?

• The ratio becomes undefined

• The ratio decreases

• The ratio remains equivalent

• The ratio increases

Which of the following is not a correct method to find equivalent ratios?

• Dividing the numerator and denominator by different numbers

• Multiplying the numerator and denominator by the same number

• None of the above
