To convert 2 1/4 inches to millimeters, you can follow these steps:
1. First, convert the whole number part of the measurement to millimeters. Since 1 inch is equal to 25.4 millimeters, you can multiply 2 inches by 25.4 to get 50.8 millimeters.
2. Next, convert the fractional part of the measurement to millimeters. To do this, you can divide the fractional part (1/4) by the denominator (4) and then multiply the result by 25.4. In this case, (1/4) รท 4 = 0.25, and 0.25 x 25.4 = 6.35 millimeters.
3. Finally, add the two results together to get the total measurement in millimeters. 50.8 + 6.35 = 57.15 millimeters.
Therefore, 2 1/4 inches is equal to 57.15 millimeters.
Real-life example:
If you have a ruler that measures 2 1/4 inches and you want to know the equivalent measurement in millimeters, you can use the above steps to convert it. This can be helpful when working on a project that requires precise measurements in millimeters.
