First, simplify the expression inside the parentheses:41кг120г - 39кг280г = 2кг840г
Now subtract the expressions:33кг120г ÷ 2кг840г = 13
Therefore, the simplified result is 13.
First, convert ц to grams (1 ц = 100g):30ц2кг = 301000g + 2kg = 30,000g + 2000g = 32,000g19ц48кг = 19100g + 48kg = 1900g + 4800g = 6700g
Now subtract the expressions:32,000g - 6700g = 25,300g
Now multiply by 720:25,300g × 720 = 18,216,000g
Therefore, the simplified result is 18,216,000g.

To simplify the expression (30ц2кг-19ц48кг)×720:First, convert ц to grams (1 ц = 100g):
30ц2кг = 301000g + 2kg = 30,000g + 2000g = 32,000g
19ц48кг = 19100g + 48kg = 1900g + 4800g = 6700g
Now subtract the expressions:
32,000g - 6700g = 25,300g
Now multiply by 720:
25,300g × 720 = 18,216,000g
Therefore, the simplified result is 18,216,000g.
