Question

6дм2см5мм+3дм45мм= ? 14км52м-7км957м=?

Answer 1

1)6ДМ=60СМ+2СМ+5ММ+30СМ+45ММ=92СМ50ММ
50ММ=5СМ,97СМ
2)1КМ=1000М
14052М-7957М=6095М=6КМ95М

Answer 2

To solve these arithmetic operations, let's convert all the measurements to the same unit. We'll use meters (m) as the common unit.

1. 6 dm 2 cm 5 mm = 6 * 10 dm + 2 * 10 cm + 5 * 1 mm = 60 dm + 20 cm + 5 mm Converting cm to dm: 20 cm = 2 dm Converting mm to cm: 5 mm = 0.5 cm Now, we can add all the measurements in dm: 60 dm + 2 dm + 0.5 dm = 62.5 dm Finally, converting dm to m: 62.5 dm = 6.25 m

So, 6 dm 2 cm 5 mm is equal to 6.25 meters.

2. 3 dm 45 mm = 3 * 10 dm + 45 * 1 mm = 30 dm + 45 mm Converting mm to dm: 45 mm = 4.5 dm Now, we can add all the measurements in dm: 30 dm + 4.5 dm = 34.5 dm Finally, converting dm to m: 34.5 dm = 3.45 m

So, 3 dm 45 mm is equal to 3.45 meters.

Now, let's perform the calculations:

1. 6.25 m + 3.45 m = 9.7 m

Therefore, 6 dm 2 cm 5 mm + 3 dm 45 mm = 9.7 meters.

3. 14 km 52 m - 7 km 957 m = (14 km * 1000) + 52 m - (7 km * 1000 + 957 m) Converting km to m: 14 km = 14 * 1000 m = 14,000 m Converting km to m: 7 km = 7 * 1000 m = 7,000 m Now, we can subtract the measurements: 14,000 m + 52 m - 7,000 m - 957 m = 14,052 m - 7,957 m Performing the subtraction: 14,052 m - 7,957 m = 6,095 m

Therefore, 14 km 52 m - 7 km 957 m = 6,095 meters.
