To convert 5 2 to cm, we first need to understand that 1 inch is equal to 2.54 cm.
Step by step instructions:
1. Start with the given value in inches, which is 5 2.
2. Convert the whole number part, which is 5, to inches by multiplying it by 2.54.
5 inches * 2.54 cm/inch = 12.7 cm
3. Convert the fraction part, which is 2, to inches by dividing it by 16 (since there are 16 inches in a foot).
