Fractions and Whole Numbers

[mathxteacher]

• If you add 2 fractions and the sum is greater than ½, what can you say about the fractions?

• If you add 2 fractions and the sum is greater than 1, what can you say about the fractions?

• If you add 2 fractions, and the sum is more than 1 ½, what can you say about the fraction?

• If you add 2 whole numbers together and the sum is larger than 10, what do you know about those 2 numbers?
• What about 100? What about 150?

1. If you add 2 fractions and the sum is greater than ½, what can you say about the fractions?

2. If you add 2 fractions and the sum is greater than 1, what can you say about the fractions?

3. If you add 2 fractions, and the sum is more than 1 ½, what can you say about the fraction?

4. If you add 2 whole numbers together and the sum is larger than 10, what do you know about those 2 numbers?

5. What about 100? What about 150?

I have no idea what they're wanting here. What were the answers for similar worked examples in class and in the textbook?

Please be complete. Thank you!

Without any other restrictions, that is about all you can say. For example suppose that you add two fractions and the sum is greater than ½. Pick any fraction you like and call it a then let b be any other fraction satisfying b>½-a, for example b=\(\displaystyle \frac{37}{73}\)-a. Then
a+b = \(\displaystyle \frac{37}{73}\) > ½
