Compare and sort in ascending order the two ordinary fractions, which one is larger: 5/4 and 13/10. Ordinary fractions compared and sorted in ascending order, result explained below

Compare: 5/4 and 13/10

The operation of comparing fractions:
5/4 and 13/10

Reduce (simplify) fractions to their lowest terms equivalents:

5/4 already reduced to the lowest terms;
the numerator and denominator have no common prime factors:
5 is a prime number;
4 = 22;


13/10 already reduced to the lowest terms;
the numerator and denominator have no common prime factors:
13 is a prime number;
10 = 2 × 5;

To sort fractions in ascending order, build up their denominators the same.

Calculate LCM, the least common multiple of the denominators of the fractions.

LCM will be the common denominator of the compared fractions.
In this case, LCM is also called LCD, the least common denominator.

The prime factorization of the denominators:


4 = 22


10 = 2 × 5


Multiply all the unique prime factors, by the largest exponents:


LCM (4, 10) = 22 × 5 = 20

Calculate the expanding number of each fraction

Divide LCM by the denominator of each fraction:


For fraction: 5/4 is 20 ÷ 4 = (22 × 5) ÷ 22 = 5


For fraction: 13/10 is 20 ÷ 10 = (22 × 5) ÷ (2 × 5) = 2



Expand the fractions

Build up all the fractions to the same denominator (which is LCM).
Multiply the numerators and denominators by their expanding number:

5/4 = (5 × 5)/(5 × 4) = 25/20


13/10 = (2 × 13)/(2 × 10) = 26/20



The fractions have the same denominator, compare their numerators.

The larger the numerator the larger the positive fraction.

The final answer:

The fractions sorted in ascending order:
25/20 < 26/20

The initial fractions in ascending order:
5/4 < 13/10

Tutoring: Comparing ordinary fractions

How to compare two fractions?

1. Fractions that have different signs:

2. A proper and an improper fraction:

3. Fractions that have both like numerators and denominators:

4. Fractions that have unlike (different) numerators but like (equal) denominators.

5. Fractions that have unlike (different) denominators but like (equal) numerators.

6. Fractions that have different denominators and numerators (unlike denominators and numerators).
