Answer 2

Sure, I can help you with these math problems! Here are the solutions:

1. 24 km 506 m × 3 = 73 km 518 m

To multiply, we can first ignore the units and just multiply the numbers: 24,506 × 3 = 73,518. Then we put the units back in to get the final answer: 73 km 518 m.

2. 78 t 123 kg × 5 = 390 t 615 kg

Again, we ignore the units and multiply the numbers: 78,123 × 5 = 390,615. Then we put the units back in to get the final answer: 390 t 615 kg.

3. 2 m 375 mm × 8 = 19 m

We need to convert the length to meters first, since the question asks for the answer in meters. 2 m 375 mm is equal to 2.375 m. Then we can multiply: 2.375 × 8 = 19. Finally, we convert back to meters: 19 m.

4. 73 m 50 mm + 9 m 25 mm = 82 m 75 mm

We can add the two lengths directly, but first we need to make sure they are in the same units. We can convert millimeters to meters by dividing by 1000: 73 m 0.050 m + 9 m 0.025 m = 82 m 0.075 m = 82 m 75 mm.

5. 96 t 509 kg - 48 t 765 kg = 47 t 744 kg

We can subtract the two weights directly, but first we need to make sure they are in the same units. We can convert kilograms to metric tons by dividing by 1000: 96 t 509 kg - 48 t 765 kg = 96.509 t - 48.765 t = 47.744 t.

6. 300 km 450 m - 195 km 728 m = 104 km 722 m

We can subtract the two lengths directly, but first we need to make sure they are in the same units: 300 km 450 m - 195 km 728 m = 104 km (450 m - 728 m). We can subtract the meters: 450 m - 728 m = -278 m. But since we can't have negative meters, we need to "borrow" 1 km (1000 m) from the kilometers: 104 km - 1 km = 103 km, and 1000 m - 278 m = 722 m. So the final answer is 103 km 722 m.

7. 42 m 14 cm ÷ 43 = 0 m 98 cm (or 0.98 m)

We can divide the length by 43 directly, but first we need to convert everything to centimeters: 42 m 14 cm = 4214 cm. Then we can divide: 4214 ÷ 43 = 98, remainder 20. The quotient is 98, which is the number of whole 43's in 4214 cm. The remainder of 20 cm is less than 43, so it represents the fractional part of the answer: 20/43 of a meter, or 0.465 m. So the final answer is 0 m 98 cm (or 0.98 m).

8. 26 s 19 kg ÷ 27 = 0 s 970 g (or 0.97 kg)

We can divide the weight by 27 directly, but first we need to convert everything to grams:
