Question

1. reading metric measurements review

record the length of the line to the nearest tenth of a centimeter (decimal) and to the nearest millimeter (whole number).
31 of 46

Explanation:

Step1: Identify the scale

The ruler has markings for centimeters and millimeters. Each centimeter is divided into 10 millimeters.

Step2: Locate the start and end points

Assume the line starts at 43.0 cm (exact marking). The end point is at 50.0 cm (exact marking).

Step3: Calculate the length in centimeters

The length \( L = 50.0 - 43.0=7.0\) cm (to the nearest tenth of a centimeter).

Step4: Convert to millimeters

Since \(1\) cm \( = 10\) mm, \(7.0\) cm \(=7.0\times10 = 70\) mm (to the nearest whole - number millimeter).

Answer:

7.0 cm, 70 mm
