Answer 3

Comparing Quantities Using Decimal Fractions

To compare the given quantities, we can convert them into decimal fractions and then compare them. Let's compare each pair of quantities:

1. 3 kg 485 g and 4 kg 80 g: - Converting to decimal fractions: - 3 kg 485 g = 3.485 kg - 4 kg 80 g = 4.080 kg - Comparing the decimal fractions: - 3.485 kg < 4.080 kg

2. 8 km 610 m and 8 km 490 m: - Converting to decimal fractions: - 8 km 610 m = 8.610 km - 8 km 490 m = 8.490 km - Comparing the decimal fractions: - 8.610 km > 8.490 km

3. 5 t 7 kg and 7 t 500 kg: - Converting to decimal fractions: - 5 t 7 kg = 5.007 t - 7 t 500 kg = 7.500 t - Comparing the decimal fractions: - 5.007 t < 7.500 t

4. 6 kg 310 g and 9 kg 50 g: - Converting to decimal fractions: - 6 kg 310 g = 6.310 kg - 9 kg 50 g = 9.050 kg - Comparing the decimal fractions: - 6.310 kg < 9.050 kg

5. 3 hours 40 minutes and 2 hours 50 minutes: - Converting to decimal fractions: - 3 hours 40 minutes = 3.67 hours - 2 hours 50 minutes = 2.83 hours - Comparing the decimal fractions: - 3.67 hours > 2.83 hours

6. 26 minutes 9 seconds and 43 minutes 16 seconds: - Converting to decimal fractions: - 26 minutes 9 seconds = 26.15 minutes - 43 minutes 16 seconds = 43.27 minutes - Comparing the decimal fractions: - 26.15 minutes < 43.27 minutes

Therefore, the comparisons are as follows:

- 3 kg 485 g < 4 kg 80 g - 8 km 610 m > 8 km 490 m - 5 t 7 kg < 7 t 500 kg - 6 kg 310 g < 9 kg 50 g - 3 hours 40 minutes > 2 hours 50 minutes - 26 minutes 9 seconds < 43 minutes 16 seconds

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