Question

2т - 3кг = 2т - 3ц = 2т : 2кг= 2т : 2ц= 5т4ц:9= 5т4ц:9ц=

Answer 1

1. 2003 кг или 0,005 т.

2. 23 центнера или 0. 5 т.

3.  1000 кг.

4. 1 ц

5. 9

6. 9 ц

Answer 2

To simplify the given expressions, let's perform the calculations step by step:

1. 2т - 3кг: Since both terms have the same unit (т), we can directly subtract the coefficients: 2т - 3кг = (2 - 3)т = -1т

2. 2т - 3ц: The units are different (т and ц), so we cannot directly subtract them. The result remains as 2т - 3ц.

3. 2т : 2кг: Divide the coefficient of т by the coefficient of кг: 2т ÷ 2кг = (2 ÷ 2)т = 1т

4. 2т : 2ц: Since the units are different (т and ц), we cannot directly divide them. The result remains as 2т : 2ц.

5. 5т4ц : 9: To simplify this expression, we need to convert ц to т. Since 100 ц = 1т, we can write: 5т4ц = 5т + 4ц ÷ 100. Now, divide the resulting expression by 9: 5т4ц ÷ 9 = (5т + 4ц ÷ 100) ÷ 9

6. 5т4ц : 9ц: Now, we need to convert both 5т and 4ц to ц to make the units consistent. We know that 1т = 100 ц, so: 5т = 5т × 100 ц/т = 500ц 4ц = 4ц

Now, the expression becomes: 5т4ц : 9ц = (500ц + 4ц) ÷ 9ц

After simplification, we get: 5т4ц : 9 = (5т + 4ц ÷ 100) ÷ 9 = 5/9 т + 4/900 т = 5/9 т + 1/225 т = (5 + 1)/9 т = 6/9 т = 2/3 т

5т4ц : 9ц = (500ц + 4ц) ÷ 9ц = 504/9 ц = 56 ц

So, the final simplified expressions are: 2т - 3кг = -1т 2т - 3ц = 2т - 3ц 2т : 2кг = 1т 2т : 2ц = 2т : 2ц 5т4ц : 9 = 2/3 т 5т4ц : 9ц = 56 ц
