Answer 3

Comparing Fractions

To compare fractions, we need to determine which fraction is greater or if they are equal. We can do this by finding a common denominator and comparing the numerators. Let's compare the given fractions:

1. 1/20 and 1/25: To compare these fractions, we can find a common denominator, which in this case is 100. Multiplying the numerator and denominator of each fraction by the same number will not change the value of the fraction. By doing this, we get: - 1/20 = 5/100 - 1/25 = 4/100

Since 5/100 is greater than 4/100, 1/20 > 1/25.

2. 10/9 and 9/10: To compare these fractions, we can find a common denominator, which in this case is 90. By doing this, we get: - 10/9 = 100/90 - 9/10 = 81/90

Since 100/90 is greater than 81/90, 10/9 > 9/10.

3. 2/15 and 19/20: To compare these fractions, we can find a common denominator, which in this case is 60. By doing this, we get: - 2/15 = 8/60 - 19/20 = 57/60

Since 57/60 is greater than 8/60, 19/20 > 2/15.

4. 5/4 and 7/6: To compare these fractions, we can find a common denominator, which in this case is 12. By doing this, we get: - 5/4 = 15/12 - 7/6 = 14/12

Since 15/12 is greater than 14/12, 5/4 > 7/6.

5. 3/8 and 3/10: To compare these fractions, we can find a common denominator, which in this case is 40. By doing this, we get: - 3/8 = 15/40 - 3/10 = 12/40

Since 15/40 is greater than 12/40, 3/8 > 3/10.

6. 8/11 and 11/8: These fractions have different denominators, so we can't directly compare them. However, we can convert them to decimals and compare the decimal values: - 8/11 ≈ 0.727 - 11/8 ≈ 1.375

Since 1.375 is greater than 0.727, 11/8 > 8/11.

7. 2/7 and 3/4: These fractions have different denominators, so we can't directly compare them. However, we can convert them to decimals and compare the decimal values: - 2/7 ≈ 0.286 - 3/4 = 0.75

Since 0.75 is greater than 0.286, 3/4 > 2/7.

8. 3/4 and 5/6: To compare these fractions, we can find a common denominator, which in this case is 12. By doing this, we get: - 3/4 = 9/12 - 5/6 = 10/12

Since 10/12 is greater than 9/12, 5/6 > 3/4.

9. 5/3 and 5/2: These fractions have different denominators, so we can't directly compare them. However, we can convert them to decimals and compare the decimal values: - 5/3 ≈ 1.667 - 5/2 = 2.5

Since 2.5 is greater than 1.667, 5/2 > 5/3.

10. 6/5 and 14/17: These fractions have different denominators, so we can't directly compare them. However, we can convert them to decimals and compare the decimal values: - 6/5 = 1.2 - 14/17 ≈ 0.824

Since 1.2 is greater than 0.824, 6/5 > 14/17.

11. 7/9 and 3/8: To compare these fractions, we can find a common denominator, which in this case is 72. By doing this, we get: - 7/9 = 56/72 - 3/8 = 27/72

Since 56/72 is greater than 27/72, 7/9 > 3/8.

12. 8/5 and 10/7: These fractions have different denominators, so we can't directly compare them. However, we can convert them to decimals and compare the decimal values: - 8/5 = 1.6 - 10/7 ≈ 1.429

Since 1.6 is greater than 1.429, 8/5 > 10/7.

13. 11/20 and 11/25: To compare these fractions, we can find a common denominator, which in this case is 100. By doing this, we get: - 11/20 = 55/100 - 11/25 = 44/100

Since 55/100 is greater than 44/100, 11/20 > 11/25.

14. 97/100 and 7/8: To compare these fractions, we can find a common denominator, which in this case is 800. By doing this, we get: - 97/100 = 776/800 - 7/8 = 700/800

Since 776/800 is greater than 700/800, 97/100 > 7/8.

15. 16/21 and 5/18: To compare these fractions, we can find a common denominator, which in this case is 378. By doing this, we get: - 16/21 = 192/378 - 5/18 = 70/378

Since 192/378 is greater than 70/378, 16/21 > 5/18.

16. 11/12 and 10/11: To compare these fractions, we can find a common denominator, which in this case is 132. By doing this, we get: - 11/12 = 121/132 - 10/11 = 120/132

Since 121/132 is greater than 120/132, 11/12 > 10/11.

I hope this helps! Let me know if you have any further questions.
