Question

use your double number line to complete the sentence.
centimeters: 0, 25, 100
meters: 0, \frac{1}{4}, 1

Explanation:

Step1: Identify centimeter-meter ratio

From the number line, 25 cm = $\frac{1}{4}$ m, 100 cm = 1 m.

Step2: Generalize the conversion

Since 100 cm = 1 m, 1 cm = $\frac{1}{100}$ m.

Step3: Complete the proportional relationship

For any centimeter value $c$, meters $m = \frac{c}{100}$.

Answer:

1 centimeter is equal to $\frac{1}{100}$ meters, and 25 centimeters is equal to $\frac{1}{4}$ meters, 100 centimeters is equal to 1 meter. (The core completed sentence based on the double line: $\boldsymbol{100}$ centimeters = $\boldsymbol{1}$ meter, and $\boldsymbol{25}$ centimeters = $\boldsymbol{\frac{1}{4}}$ meters)
