Ratio from Decimal Formula
The following formula is used to calculate the Ratio from Decimal.
D=\frac{a}{b}\ \Rightarrow\ R=a:b- Where D is the decimal value
- a is the numerator when D is written as a simplified fraction a/b
- b is the denominator when D is written as a simplified fraction a/b
- R is the corresponding ratio written as a:b (unitless)
How to Calculate Ratio from Decimal?
The following example problems outline how to calculate Ratio from Decimal.
Example Problem #1:
- First, determine the decimal value, D.
- The decimal value is given as: 0.75.
- Finally, convert D to a simplified fraction a/b and write the ratio as a:b.
D = a/b → R = a:b
The values given above are inserted into the process below and the solution is calculated:
D = 0.75 = 75/100 = 3/4, so R = 3:4
Example Problem #2:
For this problem, the variables required are provided below:
Decimal value, D = 0.80
Test your knowledge using the equation and check your answer with the calculator above.
R = a:b = ?
