To convert millimeters (mm) to centimeters (cm), we divide by 10 since there are 10 millimeters in a centimeter. Therefore, \(1\) mm is equal to \(0.1\) cm.
2. \(400\) cm to m
To convert centimeters (cm) to meters (m), we divide by 100 since there are 100 centimeters in a meter. Therefore, \(400\) cm is equal to \(4\) m.
3. \(5\) km to m
To convert kilometers (km) to meters (m), we multiply by 1000 since there are 1000 meters in a kilometer. Therefore, \(5\) km is equal to \(5000\) m.
4. \(1\) km to cm
To convert kilometers (km) to centimeters (cm), we multiply by 100000 since there are 100000 centimeters in a kilometer. Therefore, \(1\) km is equal to \(100000\) cm.

B. Find the area (hectare) of the following:
1. \(600\) m x \(600\) m
To find the area of a rectangle, we multiply its length by its width. Therefore, the area of a rectangle with a length of \(600\) m and a width of \(600\) m is \(360000\) square meters. Since there are \(36\) hectares.
2. \(100\) m x \(1000\) m
Similarly10000\) square meters in a hectare, the area is \(, the area of a rectangle with a length of \(100\) m and a width of \(1000\) m is \(100000\) square meters or \(10\) hectares.
3. \(200\) mac x \(300\) m
It seems there's an error in the unit provided. "mac" is not a recognized unit. Please provide the correct unit, and I'll be happy to assist you with finding the area.
4. \(300\) m x \(400\) m
The area of a rectangle with a length of \(300\) m and a width of \(400\) m is \(120000\) square meters or \(12\) hectares.
5. \(300\) m x \(600\) m
The area of a rectangle with a length of \(300\) m and a width of \(600\) m is \(180000\) square meters or \(18\) hectares.
Compute the following:
1. \(6\%\) of \(100\) plants were replaced
To calculate \(6\%\) of \(100\) plants, we multiply \(100\) by \(0.06\) (which is \(6\%\) as a decimal). The result is \(6\) plants.
2. \(2.15\%\) of \(28\) hectares are harvested
To calculate \(2.15\%\) of \(28\) hectares, we multiply \(28\) by \(0.0215\) (which is \(2.15\%\) as a decimal). The result is \(0.602\) hectares.
3. \(80\%\) of \(90\) farmers are present
To calculate \(80\%\) of \(90\) farmers, we multiply \(90\) by \(0.8\) (which is \(80\%\) as a decimal). The result is \(72\) farmers.
4. \(50\) N of \(P200\) increase in farmers' salary
It seems there's an error or missing information in the question. Please provide the complete information, and I'll be happy to assist you with the computation.
5. \(5\%\) of \(100\) kg seeds are dormant
To calculate \(5\%\) of \(100\) kg seeds, we multiply \(100\) by \(0.05\) (which is \(5\%\) as a decimal). The result is \(5\) kg seeds.
Answers & Comments
Answer:
A. Convert the following:
1. \(1\) mm to cm
To convert millimeters (mm) to centimeters (cm), we divide by 10 since there are 10 millimeters in a centimeter. Therefore, \(1\) mm is equal to \(0.1\) cm.
2. \(400\) cm to m
To convert centimeters (cm) to meters (m), we divide by 100 since there are 100 centimeters in a meter. Therefore, \(400\) cm is equal to \(4\) m.
3. \(5\) km to m
To convert kilometers (km) to meters (m), we multiply by 1000 since there are 1000 meters in a kilometer. Therefore, \(5\) km is equal to \(5000\) m.
4. \(1\) km to cm
To convert kilometers (km) to centimeters (cm), we multiply by 100000 since there are 100000 centimeters in a kilometer. Therefore, \(1\) km is equal to \(100000\) cm.
