A mechanic's ruler uses decimal parts of an inch instead of fractions. The ruler reads decimals to the ten-thousandths place. What decimal would the mechanic look for on the ruler to see if a part was 3/8 inch in diameter?
Divide the numerator by the denominator.
3/8 = 0.375
To find the decimal measurement on the ruler for a part that is 3/8 inch in diameter, you can convert the fraction to a decimal.
To convert 3/8 to a decimal, divide the numerator (3) by the denominator (8):
3 ÷ 8 = 0.375
So, the decimal measurement on the ruler to look for would be 0.375.
