How to Convert 0.05 to a Fraction
Converting any terminating decimal into a simplified fraction involves three straightforward mathematical steps:
Step 1: Identify the Place Value
Look at the position of the last digit in 0.05:
- The tenths place has a 0.
- The hundredths place has a 5.
Because the number extends two decimal places to the right of the decimal point, the denominator is 100. This gives the unsimplified fraction:
Step 2: Find the Greatest Common Divisor (GCD)
To find what is 0.05 as a fraction in its simplest form, determine the largest number that divides evenly into both the numerator (5) and the denominator (100):
- Factors of 5: 1, 5
- Factors of 100: 1, 2, 4, 5, 10, 20, 25, 50, 100
- Greatest Common Divisor (GCD) = 5
Both 5 and 100 can be divided evenly by 5.
Step 3: Divide the Numerator and Denominator
Divide both parts of the fraction by 5:
Final Answer
Therefore, 0.05 as a fraction in simplest form is:
How to Write 0.05 Inches as a Fraction in Simplest Form
In engineering, machining, woodworking, and 3D printing, decimal measurements on calipers often need to be matched against standard fractional drill bits or imperial rulers.
To write 0.05 inches as a fraction in simplest form:
-
Express the decimal as a fraction:
Write 0.05 inches over 1 inch:
0.05 / 1 -
Multiply the numerator and denominator by 100:
This removes the decimal point:
5 / 100 -
Simplify by dividing both numbers by 5:
(5 ÷ 5) / (100 ÷ 5) = 1/20 inch
Final Answer
0.05 inches as a simplified fraction is:
Equivalent to 50 thousandths of an inch (50 thou or 50 mils).
Machining Note
Standard US imperial drill bits and tape measures typically use powers of two (1/16, 1/32, 1/64).
While 0.05 inches equals exactly 1/20 inch, it is not a standard fractional ruler marking. Its closest common fractional equivalents are:
- 3/64 inch = 0.046875 inches
- 1/16 inch = 0.0625 inches
The closest of these two measurements is 3/64 inch, although neither is an exact match for 0.05 inches.
