Question

(6кг 130г+8кг 800г)×3 (2ц 98кг+5ц 35кг)÷7 (6км 82м+35км 92м)÷7 (5м 72см+4м 8см)×6

Answer 1

Нужно знать: 1 кг = 1000 г, 1 ц = 100 кг, 1 км = 1000 м, 1 м = 100 см.

(6 кг 130 г + 8 кг 800 г) · 3  = 14 кг 930 г · 3 = 14 930 г · 3 =

= 44 790 г = 44 кг 790 г

(2 ц 98 кг + 5 ц 35 кг) : 7  = 7 ц 133 кг : 7 = 8 ц 33 кг : 7 =

= 833 кг : 7 = 119 кг = 1 ц 19 кг

(6 км 82 м + 35 км 92 м) : 7 = 41 км 174 м : 7 = 41 174 м : 7 =

=  5 882 м = 5 км 882 м

(5 м 72 см + 4 м 8 см) · 6 = 9 м 80 см · 6 = 980 см · 6 =

= 5 880 см = 58 м 80 см

Answer 2

To perform the calculations, let's convert the given quantities to a consistent unit and then solve the equations.

1. (6kg 130g + 8kg 800g) × 3:

First, let's convert the masses to grams: 6kg = 6,000g 130g + 8,800g = 8,930g

Now we can add the masses and multiply by 3: (6,000g + 8,930g) × 3 = 14,930g × 3 = 44,790g

Therefore, (6kg 130g + 8kg 800g) × 3 is equal to 44,790 grams.

2. (2c 98kg + 5c 35kg) ÷ 7:

To convert centners to kilograms, we multiply by 100: 2c = 2 × 100kg = 200kg 5c = 5 × 100kg = 500kg

Now we can add the masses and divide by 7: (200kg + 500kg) ÷ 7 = 700kg ÷ 7 = 100kg

Therefore, (2c 98kg + 5c 35kg) ÷ 7 is equal to 100 kilograms.

3. (6km 82m + 35km 92m) ÷ 7:

To convert kilometers to meters, we multiply by 1,000: 6km = 6 × 1,000m = 6,000m 35km = 35 × 1,000m = 35,000m

Now we can add the distances and divide by 7: (6,000m + 35,000m) ÷ 7 = 41,000m ÷ 7 = 5,857.14m

Therefore, (6km 82m + 35km 92m) ÷ 7 is approximately equal to 5,857.14 meters.

4. (5m 72cm + 4m 8cm) × 6:

First, let's convert the centimeters to meters: 72cm = 0.72m 8cm = 0.08m

Now we can add the lengths and multiply by 6: (5m + 0.72m + 4m + 0.08m) × 6 = (9.8m) × 6 = 58.8m

Therefore, (5m 72cm + 4m 8cm) × 6 is equal to 58.8 meters.
