Answer 3

I can help you with your math question. To express 45 dm 7 cm 2 mm in meters and write it as a decimal fraction, you need to convert each unit to meters and add them together. One decimeter is equal to 0.1 meter, one centimeter is equal to 0.01 meter, and one millimeter is equal to 0.001 meter. Therefore, 45 dm 7 cm 2 mm is equal to:

$$45 \times 0.1 + 7 \times 0.01 + 2 \times 0.001 = 4.5 + 0.07 + 0.002 = 4.572$$

So, the answer is 4.572 meters. You can use an online calculator to convert different units of length to meters . I hope this helps. Have a nice day.
