Answer 2

To convert the given measurements, let's break down each equation and solve step by step:

1. 5m + 3dm = ? mm To convert meters to millimeters, we know that there are 1000 millimeters in 1 meter. Therefore, we can calculate: 5m = 5 * 1000mm = 5000mm 3dm = 3 * 100mm = 300mm Adding these together, we get: 5m + 3dm = 5000mm + 300mm = 5300mm

2. 3dm^2 + 9cm^2 = ? cm^2 To find the area of a square, we need to square the side length. In this case, we have a square with sides measuring 3dm and 9cm. Converting them to centimeters: 3dm = 3 * 10cm = 30cm 9cm^2 = 9cm * 9cm = 81cm^2 Adding these together, we get: 3dm^2 + 9cm^2 = 30cm^2 + 81cm^2 = 111cm^2

3. 120ц = ? kg To convert centners to kilograms, we know that there are 100 kilograms in 1 centner. Therefore, we can calculate: 120ц = 120 * 100kg = 12000kg

4. 8cm + 5mm = ? mm To convert centimeters to millimeters, we know that there are 10 millimeters in 1 centimeter. Therefore, we can calculate: 8cm = 8 * 10mm = 80mm 5mm = 5mm Adding these together, we get: 8cm + 5mm = 80mm + 5mm = 85mm

5. 23m + 6cm = ? cm To convert meters to centimeters, we know that there are 100 centimeters in 1 meter. Therefore, we can calculate: 23m = 23 * 100cm = 2300cm 6cm = 6cm Adding these together, we get: 23m + 6cm = 2300cm + 6cm = 2306cm

6. 12т = ? ц To convert tons to centners, we know that there are 10 centners in 1 ton. Therefore, we can calculate: 12т = 12 * 10ц = 120ц

7. 620с = ? мин To convert seconds to minutes, we know that there are 60 seconds in 1 minute. Therefore, we can calculate: 620с = 620 / 60 мин = 10 мин

8. 48dm + 5cm = ? cm To convert decimeters to centimeters, we know that there are 10 centimeters in 1 decimeter. Therefore, we can calculate: 48dm = 48 * 10cm = 480cm 5cm = 5cm Adding these together, we get: 48dm + 5cm = 480cm + 5cm = 485cm

9. 2355кг = ? т To convert kilograms to tons, we know that there are 0.001 tons in 1 kilogram. Therefore, we can calculate: 2355кг = 2355 * 0.001т = 2.355т

I hope this helps! Let me know if you have any further questions.
