Precision and Rounding in Measurements

When dealing with measurements, it is important to understand how to express them with a specified level of precision and rounding. In this case, we are asked to write down measurements with a precision of 1 decimeter (dm) and indicate whether there is a deficiency, excess, or rounding according to the given example.

The example provided states that 6 dm 7 cm is approximately equal to 6 dm with a deficiency, and also approximately equal to 7 dm with an excess and rounding.

Let's solve the given examples:

а) 7 dm 6 cm: - With a precision of 1 dm, we round the centimeters to the nearest decimeter. - Since 6 cm is closer to 0 cm than to 10 cm, we round down to 7 dm with a deficiency.

б) 8 dm 4 cm: - Rounding 4 cm to the nearest decimeter, we find that it is closer to 0 cm than to 10 cm. - Therefore, we have 8 dm with a deficiency.

в) 3 dm 5 cm: - Rounding 5 cm to the nearest decimeter, we find that it is closer to 10 cm than to 0 cm. - Thus, we have 4 dm with an excess and rounding.

г) 1 m 8 dm 3 cm: - Converting 1 m to decimeters, we have 10 dm. - Adding 8 dm and rounding 3 cm to the nearest decimeter, we find that it is closer to 0 cm than to 10 cm. - Therefore, we have 18 dm with a deficiency.

д) 4 m 5 dm 6 cm: - Converting 4 m to decimeters, we have 40 dm. - Adding 5 dm and rounding 6 cm to the nearest decimeter, we find that it is closer to 10 cm than to 0 cm. - Thus, we have 46 dm with an excess and rounding.

е) 7 m 4 dm 5 cm: - Converting 7 m to decimeters, we have 70 dm. - Adding 4 dm and rounding 5 cm to the nearest decimeter, we find that it is closer to 0 cm than to 10 cm. - Therefore, we have 74 dm with a deficiency.

ж) 29 cm: - Since the precision required is 1 dm, we need to convert centimeters to decimeters. - Rounding 29 cm to the nearest decimeter, we find that it is closer to 30 cm than to 20 cm. - Thus, we have 3 dm with an excess and rounding.

з) 41 cm: - Rounding 41 cm to the nearest decimeter, we find that it is closer to 40 cm than to 50 cm. - Therefore, we have 4 dm with a deficiency.

и) 235 cm: - Rounding 235 cm to the nearest decimeter, we find that it is closer to 240 cm than to 230 cm. - Thus, we have 24 dm with an excess and rounding.

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