Write the equality and two conversion factors for each of the following pairs of units:
a. centimeters and inches

검증된 단계별 안내
1
Step 1: Understand the relationship between centimeters and inches. The standard conversion factor is that 1 inch is equal to 2.54 centimeters.
Step 2: Write the equality based on the relationship: 1 inch = 2.54 cm.
Step 3: Create the first conversion factor by expressing the equality as a fraction: \( \frac{1 \text{ inch}}{2.54 \text{ cm}} \). This conversion factor is used to convert centimeters to inches.
Step 4: Create the second conversion factor by inverting the fraction: \( \frac{2.54 \text{ cm}}{1 \text{ inch}} \). This conversion factor is used to convert inches to centimeters.
Step 5: Verify that both conversion factors are consistent with the equality and can be used interchangeably depending on the direction of the conversion.
