80км -36км 220м= ? 16кг90г+4кг 985г= ? 95сом 35тый-69тый= ? 18см 2мм-9мм=?

Answer 1

Ответ:

Пошаговое объяснение:

Переводим меньшее в большее(или наоборот)

В 1 км - 1000м

220:1000=0.22

36+0.22=36.22

80-36.22=43.78км(42км780м)

Answer 2

Let's solve each of the expressions step by step:

1. 80 km - 36 km 220 m: To subtract distances, we need to make sure all units are the same. We can convert 36 km to meters and then subtract:

80 km - 36 km = 80,000 m - 36,000 m = 44,000 m Now, we subtract the remaining 220 m: 44,000 m - 220 m = 43,780 m

So, 80 km - 36 km 220 m = 43,780 m.

2. 16 kg 90 g + 4 kg 985 g: To add masses, we need to make sure all units are the same. We can convert grams to kilograms and then add:

16 kg 90 g + 4 kg 985 g = 16.09 kg + 4.985 kg = 21.075 kg

So, 16 kg 90 g + 4 kg 985 g = 21.075 kg.

3. 95 som 35 tyi - 69 tyi: It seems like there might be a typo in the expression. "tyi" is not a standard unit, and it's unclear what it stands for. If you provide the correct unit or clarify the expression, I can help you with the calculation.

4. 18 cm 2 mm - 9 mm: To subtract lengths, we need to make sure all units are the same. We can convert millimeters to centimeters and then subtract:

18 cm 2 mm - 9 mm = 18 cm + (2 mm - 9 mm) = 18 cm - 7 mm Now, we need to convert 7 mm back to centimeters: 1 cm = 10 mm, so 7 mm = 7/10 cm = 0.7 cm

Finally, we can subtract: 18 cm - 0.7 cm = 17.3 cm

So, 18 cm 2 mm - 9 mm = 17.3 cm.
