Questions & Answers

Q: What are equivalent rational numbers?

Equivalent rational numbers are different numbers that represent the same value. They are not equal, but they are similar in some ways.

Q: How do you find equivalent rational numbers?

To find equivalent rational numbers, multiply the numerator and denominator by the same number. This does not change the value of the rational number.

Q: Can you give an example of finding equivalent rational numbers?

Sure! If the given rational number is 2/3, you can find equivalent rational numbers by multiplying both the numerator and denominator by the same number, such as 2/3 * 2/2 = 4/6.

Q: What should you do if the numerator and denominator are large?

If the numerator and denominator are large, you can divide them by a common factor to find equivalent rational numbers. This simplifies the calculation.

Summary & Key Takeaways

• Equivalent rational numbers are different numbers that represent the same value.

• To find equivalent rational numbers, multiply the numerator and denominator by the same number.

• If the numerator and denominator are large, divide them by a common factor to find equivalent rational numbers.
