Answer 1

1.098+d = d+1.098
(345.704+208.009)+с = (345.704+с)+208 009
560+f+140+m = (560+m)+(f+140)

Answer 2

Problem 1: Arithmetic Expression

The given arithmetic expression is: 1.098 + d + d + 1.098 + (345.704 + 208.009) + (345.704 + с) + 208 + 009 + 560 + f + 140 + m + (560 + m) + (f + 140).

To simplify this expression, we can combine like terms. Let's group the terms with the same variable together:

2d + 2.196 + 691.408 + 2с + 208009 + 560 + f + 140 + 2m

Now, let's simplify further:

2d + 693.604 + 2с + 208009 + 560 + f + 140 + 2m

Please note that the given expression contains variables (d, с, f, and m) for which we don't have specific values. Therefore, we cannot simplify the expression any further without knowing the values of these variables.

Problem 2: Harvesting Potatoes

a) From the first field, 3890 kg of potatoes were harvested, and from the third field, 9007 kg were harvested. We need to find the weight of potatoes harvested from the second field, given that the combined weight of potatoes harvested from the first and second fields is 1998 kg less than the weight harvested from the third field.

Let's set up the equation: Weight from the first field + Weight from the second field = Weight from the third field - 1998 kg

3890 + x = 9007 - 1998

To solve for x, we can simplify the equation:

x = (9007 - 1998) - 3890

x = 7009 - 3890

x = 3119 kg

Therefore, the weight of potatoes harvested from the second field is 3119 kg.

b) In this problem, we have two platforms. On one platform, there is a container with potatoes weighing 3.890 kg, and on the other platform, there is a tractor weighing 9.007 kg and a seeder weighing 1.998 kg. The total weight on both platforms is the same. We need to find the weight of the container with beets.

Let's set up the equation: Weight of container with potatoes + Weight of container with beets = Weight of tractor + Weight of seeder

3.890 + y = 9.007 + 1.998

To solve for y, we can simplify the equation:

y = (9.007 + 1.998) - 3.890

y = 11.005 - 3.890

y = 7.115 kg

Therefore, the weight of the container with beets is 7.115 kg.

Problem 3: Measuring Milk

In this problem, we have a 12-liter jug filled with milk and two empty jugs, one with a capacity of 5 liters and the other with a capacity of 7 liters. We need to measure exactly 1 liter of milk using only these jugs. We can only pour milk from one jug to another.

Here's a step-by-step solution: 1. Fill the 7-liter jug with milk from the 12-liter jug. Now, the 7-liter jug contains 7 liters of milk, and the 12-liter jug contains 5 liters of milk. 2. Empty the 7-liter jug. 3. Pour the 5 liters of milk from the 12-liter jug into the empty 7-liter jug. Now, the 7-liter jug contains 5 liters of milk, and the 12-liter jug is empty. 4. Fill the 12-liter jug with milk from the 5-liter jug. Now, the 12-liter jug contains 5 liters of milk, and the 5-liter jug contains 2 liters of milk. 5. Empty the 12-liter jug. 6. Pour the remaining 2 liters of milk from the 5-liter jug into the empty 12-liter jug. 7. Fill the 7-liter jug with milk from the 5-liter jug. Now, the 7-liter jug contains 2 liters of milk, and the 5-liter jug contains 3 liters of milk. 8. Fill the 12-liter jug with milk from the 7-liter jug. Now, the 12-liter jug contains 2 liters of milk, and the 7-liter jug contains 0 liters of milk. 9. Fill the 7-liter jug with milk from the 5-liter jug. Now, the 7-liter jug contains 3 liters of milk, and the 5-liter jug contains 0 liters of milk. 10. Pour 1 liter of milk from the 7-liter jug into the empty 5-liter jug. Now, the 7-liter jug contains 2 liters of milk, and the 5-liter jug contains 1 liter of milk.

By following these steps, we have successfully measured exactly 1 liter of milk using only the 12-liter, 7-liter, and 5-liter jugs.
