3 м 5 дм 9 см – 1 м 4 дм 4 см67 дм 5 см - 3 м 2 см6 м 9 дм 7 см - 2 м 45 см​

Answer 1

Ответ:

3м 5дм 9см - 1 м 4дм 4см = 2 м 1дм 5см

67дм 5 см-3 м 2см = 37дм 3см

6м 9дм 7см-2м 45см= 4м 5дм 2см

Answer 2

To subtract the given measurements, we need to align the units properly. Let's convert all the measurements to centimeters to simplify the calculation.

Given: 3 m 5 dm 9 cm 1 m 4 dm 4 cm 67 dm 5 cm 3 m 2 cm 6 m 9 dm 7 cm 2 m 45 cm

Converting the measurements to centimeters: 3 m = 3 * 100 cm = 300 cm 5 dm = 5 * 10 cm = 50 cm 9 cm = 9 cm

1 m = 1 * 100 cm = 100 cm 4 dm = 4 * 10 cm = 40 cm 4 cm = 4 cm

67 dm = 67 * 10 cm = 670 cm 5 cm = 5 cm

3 m = 3 * 100 cm = 300 cm 2 cm = 2 cm

6 m = 6 * 100 cm = 600 cm 9 dm = 9 * 10 cm = 90 cm 7 cm = 7 cm

2 m = 2 * 100 cm = 200 cm 45 cm = 45 cm

Now, let's subtract the measurements:

(300 cm + 50 cm + 9 cm) - (100 cm + 40 cm + 4 cm) = (359 cm) - (144 cm) = 359 cm - 144 cm = 215 cm

(670 cm + 5 cm) - (300 cm + 2 cm) = (675 cm) - (302 cm) = 675 cm - 302 cm = 373 cm

(600 cm + 90 cm + 7 cm) - (200 cm + 45 cm) = (697 cm) - (245 cm) = 697 cm - 245 cm = 452 cm

Therefore, the results of the given subtractions are:

215 cm 373 cm 452 cm
