Chapter 1, Problem 80A

To determine

To Arrange: The given numbers from most precise to least precise.

Answer to Problem 80A

  $0.0034\text{m}>45.6\text{m}>1234\text{m}$

Explanation of Solution

Introduction:

The precision of a number depends on the measurement up to as many decimal places.

  $0.0034\text{m}$ has 4 digits after decimal point, $45.6\text{m}$ has 1 digit after decimal point and $1234\text{m}$ has no digit after decimal point.

Thus, the numbers arranged in order from most precise to least precise is:

  $0.0034\text{m}>45.6\text{m}>1234\text{m}$

Conclusion:

  $0.0034\text{m}>45.6\text{m}>1234\text{m}$
