Fraction Ratio Formula:
| From: | To: |
A fraction ratio compares two fractions by dividing one by the other. It expresses the relative size or proportion between two fractional values, commonly written in the form "a:b" where the ratio represents how many times one fraction contains the other.
The fraction ratio is calculated using the formula:
Where:
Explanation: To find the ratio between two fractions, divide the first fraction by the second fraction. This is equivalent to multiplying the first fraction by the reciprocal of the second fraction.
Details: Fraction ratios are used in various fields including mathematics, chemistry for mixing solutions, cooking for recipe scaling, finance for financial ratios, and engineering for gear ratios and mechanical advantage calculations.
Tips: Enter the numerator and denominator for both fractions. All values must be positive numbers, and denominators cannot be zero. The calculator will compute and display the ratio in the form "1 : X" where X represents how many times the second fraction fits into the first.
Q1: Can I use decimal numbers in the calculator?
A: Yes, the calculator accepts decimal values for more precise calculations.
Q2: What if I get a ratio less than 1?
A: A ratio less than 1 indicates that the second fraction is larger than the first fraction. For example, a ratio of 1:0.5 means the first fraction is half the size of the second.
Q3: How do I simplify fraction ratios?
A: To simplify a fraction ratio, find the greatest common divisor of both sides of the ratio and divide both by that number.
Q4: Can fraction ratios be expressed as percentages?
A: Yes, fraction ratios can be converted to percentages by expressing the ratio as a fraction and multiplying by 100.
Q5: What's the difference between a fraction and a ratio?
A: A fraction represents a part of a whole, while a ratio compares two quantities. All fractions can be expressed as ratios, but not all ratios are fractions.
