Question

Выразите в метрах и запишите в виде десятичной дроби: 42 см 7 мм

Answer 1

(42 см 7 мм) :100=42,7 см :100=0,427 м

Answer 2

1) 125 см = 1.25 m

2) 18 см = 0.18 m

3) 4 дм 4 см = 0.44 m

4) 58 дм 6 см = 5.86 m

5) 2 см = 0.02 m

6) 4 м 6 дм 5 см = 4.65 m

Answer 3

Answer in detail. Express in meters and write as a decimal fraction: 42 cm 7 mm

To answer this question, we need to convert centimeters and millimeters to meters. One meter is equal to 100 centimeters or 1000 millimeters. Therefore, we can use the following formulas:

- To convert centimeters to meters, we divide by 100. For example, 42 cm = 42 / 100 m = 0.42 m. - To convert millimeters to meters, we divide by 1000. For example, 7 mm = 7 / 1000 m = 0.007 m.

Then, we can add the meters together to get the final answer. For example, 0.42 m + 0.007 m = 0.427 m.

Therefore, the answer is 0.427 m. This is also a decimal fraction, which means a fraction that has a denominator of a power of 10. In this case, the denominator is 1000, which is 10 to the power of 3. We can write the answer as 427 / 1000 or 0.427.
