To convert 4 3/4 to centimeters, we first need to convert the whole number part (4) and the fraction part (3/4) separately.
1. Converting the whole number part:
1 inch is equal to 2.54 centimeters. Therefore, to convert 4 inches to centimeters, we multiply 4 by 2.54:
4 inches * 2.54 cm/inch = 10.16 cm
2. Converting the fraction part:
To convert the fraction 3/4 to centimeters, we need to first convert it to a decimal. To do this, we divide 3 by 4:
3 รท 4 = 0.75
Now, we multiply this decimal by 2.54 to convert it to centimeters:
0.75 * 2.54 cm = 1.905 cm
Finally, we add the two results together to get the final answer:
10.16 cm + 1.905 cm = 12.065 cm
Therefore, 4 3/4 inches is equal to 12.065 centimeters.
Real-life example:
If you have a piece of wood that is 4 3/4 inches long and you want to know its length in centimeters, you would convert it to 12.065 centimeters. This conversion can be useful when working on DIY projects or when measuring items in different units.
