To convert 3 8 inch to decimal, we need to first understand that inches can be expressed as a fraction and then converted to a decimal format.
The fraction 3/8 represents three parts of a total of eight equal parts. When we want to convert this fraction into a decimal, we simply divide the numerator (3) by the denominator (8).
So, we perform the calculation:
3 ÷ 8 = 0.375
Now, since we have 3 inches plus the fraction, we add this value to the whole number:
3 + 0.375 = 3.375
Therefore, 3 8 inch, when converted to decimal, equals 3.375 inches.
