Comparing Fractions Calculator
Instantly determine the relationship between two fractions. This tool shows you the decimal values and the cross-multiplication logic used to compare them.
How do you compare two fractions?
To compare two fractions, you can either: 1) Find a common denominator and compare the numerators. 2) Cross-multiply: multiply the numerator of the first by the denominator of the second, and vice-versa. 3) Convert both to decimals.
What is the cross-multiplication method?
For a/b and c/d, compare (a Ć d) and (b Ć c). If ad > bc, then a/b > c/d. If ad < bc, then a/b < c/d.
How do I compare a fraction and a decimal?
The easiest way is to convert the fraction into a decimal by dividing the numerator by the denominator, then compare the two decimal values.
What if the denominators are the same?
If the denominators are already the same, simply compare the numerators. The fraction with the larger numerator is the larger fraction.
