Let's say and write the correct conversion:

[tex]\[ 10 \text{ mm} = 1 \text{ cm}, \quad 50 \text{ mm} = 5 \text{ cm} \][/tex]



Answer :

To solve the problem of converting 50 millimeters (mm) into centimeters (cm), we can use the given relationship that 10 millimeters is equivalent to 1 centimeter.

Here's a step-by-step solution:

1. Understand the Conversion Factor:
- The relationship given is: [tex]\(10 \, \text{mm} = 1 \, \text{cm}\)[/tex]

2. Identify the Value to Convert:
- We need to convert [tex]\(50 \, \text{mm}\)[/tex] into centimeters.

3. Set Up the Conversion:
- Use the conversion factor to set up the problem. Since [tex]\(10 \, \text{mm} = 1 \, \text{cm}\)[/tex], we can convert millimeters to centimeters by dividing by the conversion factor, which is 10.

4. Perform the Conversion:
- Take the value [tex]\(50 \, \text{mm}\)[/tex] and divide it by 10 to convert it to centimeters:

[tex]\[ 50 \, \text{mm} \div 10 = 5 \, \text{cm} \][/tex]

5. Conclusion:
- Therefore, [tex]\(50 \, \text{mm}\)[/tex] is equal to [tex]\(5 \, \text{cm}\)[/tex].

So, the final answer is:
[tex]\[ 50 \, \text{mm} = 5 \, \text{cm} \][/tex]
