Answer 2

Comparing Decimal Fractions

1. 5.089 and 5.1: - To compare these two decimal fractions, we can look at the whole number part first, which is 5 in both cases. Since they are the same, we move on to the decimal part. - In the first decimal fraction, 5.089, the decimal part is 0.089. - In the second decimal fraction, 5.1, the decimal part is 0.1. - Comparing the decimal parts, we can see that 0.089 is less than 0.1. - Therefore, 5.089 is less than 5.1.

2. 28.354 and 0.848: - Again, let's compare the whole number parts first. The whole number part of 28.354 is 28, while the whole number part of 0.848 is 0. - Since 28 is greater than 0, we can already conclude that 28.354 is greater than 0.848. - We don't need to compare the decimal parts in this case.

3. 117.44 and 126.56: - Comparing the whole number parts, we can see that 117 is less than 126. - Now let's compare the decimal parts. The decimal part of 117.44 is 0.44, while the decimal part of 126.56 is 0.56. - Since 0.56 is greater than 0.44, we can conclude that 126.56 is greater than 117.44.

4. 1.782 and 0.29: - Comparing the whole number parts, we can see that 1 is greater than 0. - Now let's compare the decimal parts. The decimal part of 1.782 is 0.782, while the decimal part of 0.29 is 0.29. - Since 0.782 is greater than 0.29, we can conclude that 1.782 is greater than 0.29.

5. 4.5 and 16: - Comparing the whole number parts, we can see that 4 is less than 16. - Since 4 is less than 16, we can conclude that 4.5 is less than 16. - We don't need to compare the decimal parts in this case.

6. 7 and 18.36: - Comparing the whole number parts, we can see that 7 is less than 18. - Since 7 is less than 18, we can conclude that 7 is less than 18.36. - We don't need to compare the decimal parts in this case.

7. 394.2 and 394.20: - Comparing the whole number parts, we can see that 394 is the same in both cases. - Now let's compare the decimal parts. The decimal part of 394.2 is 0.2, while the decimal part of 394.20 is 0.20. - Since 0.2 is the same as 0.20, we can conclude that 394.2 is equal to 394.20.

8. 4.32 and 4.7: - Comparing the whole number parts, we can see that 4 is the same in both cases. - Now let's compare the decimal parts. The decimal part of 4.32 is 0.32, while the decimal part of 4.7 is 0.7. - Since 0.7 is greater than 0.32, we can conclude that 4.7 is greater than 4.32.
