Answer 2

It looks like you've provided a series of mathematical equations in Russian. Let's break them down and solve them step by step.

Equation 1: 70ц - 980кг

It seems that you are subtracting 980 kilograms from 70 centners. Centner (ц) is a unit of mass, and 1 centner is equal to 100 kilograms. So, 70 centners is equal to 7000 kilograms. Therefore, the expression becomes: 70ц - 980кг = 7000кг - 980кг = 6020кг

Equation 2: 705м - 12дм

Here, you seem to be subtracting 12 decimeters from 705 meters. To perform the subtraction, we need to convert 705 meters to decimeters. Since 1 meter is equal to 10 decimeters, we have: 705м - 12дм = 7050дм - 12дм = 7038дм

Equation 3: 90ц 6кг - 26ц 97кг

In this equation, you are subtracting 26 centners 97 kilograms from 90 centners 6 kilograms. Converting centners to kilograms, we get: 90ц 6кг - 26ц 97кг = (90 * 100 + 6)кг - (26 * 100 + 97)кг = 9006кг - 2697кг = 6309кг

Equation 4: 28км 981м + 2км 687м

It appears that you are adding 28 kilometers 981 meters to 2 kilometers 687 meters. To simplify, we can add the kilometers and meters separately: 28км 981м + 2км 687м = (28 + 2)км (981 + 687)м = 30км 1668м
