Question

metric measurement the meter length and distance but what if the pencil isn’t on exact length? how would you work that out? luckily, the metric system always moves in increments of 10. each little line between the 14 and 15 equals 1/10th of a centimeter (hint: they are millimeters!). that means you can just add it on as a decimal to the whole number. pretty easy, right? what is the length of this pencil? cm

Explanation:

Step1: Identify the whole number part

The pencil starts from 0 cm (assuming the left end is at 0, and the tip is at 13.5 cm? Wait, no, looking at the ruler, the pencil's tip is at 14 cm? Wait, no, the text says between 14 and 15? Wait, no, the ruler has marks. Wait, the pencil's length: let's see, the top of the pencil is at, say, 0 cm? Wait, no, the image shows the pencil with the eraser at the top (0 cm?) and the tip at 13.5 cm? Wait, no, the text says "each little line between the 14 and 15 equals 1/10th of a centimeter (millimeters)". Wait, maybe the pencil's length is from 0 to 13.5 cm? Wait, no, let's re-examine. The ruler has cm marks. The pencil's tip is at 13.5 cm? Wait, the text says "add it on as a decimal to the whole number". So the whole number part: let's say the pencil goes from 0 to 13 cm, and then 5 millimeters (since 1 mm = 0.1 cm, so 5 mm = 0.5 cm). So 13 + 0.5 = 13.5 cm.

Step2: Calculate the decimal part

Since each small line between cm marks is 1 mm = 0.1 cm. If there are 5 small lines after 13 cm, that's 5 * 0.1 = 0.5 cm.

Step3: Sum the whole and decimal parts

Whole number (13 cm) + decimal part (0.5 cm) = 13.5 cm.

Answer:

13.5 cm
