Compare and sort in ascending order the two ordinary fractions, which one is larger: 25/10 and 28/20. Ordinary fractions compared and sorted in ascending order, result explained below

Compare: 25/10 and 28/20

The operation of comparing fractions:
25/10 and 28/20

Reduce (simplify) fractions to their lowest terms equivalents:

25/10 = 52/(2 × 5) = (52 ÷ 5)/((2 × 5) ÷ 5) = 5/2


28/20 = (22 × 7)/(22 × 5) = ((22 × 7) ÷ 22)/((22 × 5) ÷ 22) = 7/5

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:


2 is a prime number


5 is a prime number


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


LCM (2, 5) = 2 × 5 = 10

Calculate LCM, the least common multiple, online calculator


Calculate the expanding number of each fraction

Divide LCM by the denominator of each fraction:


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


For fraction: 7/5 is 10 ÷ 5 = (2 × 5) ÷ 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:

5/2 = (5 × 5)/(5 × 2) = 25/10


7/5 = (2 × 7)/(2 × 5) = 14/10



The fractions have the same denominator, compare their numerators.

The larger the numerator the larger the positive fraction.

Tutoring: Comparing ordinary fractions

How to compare two fractions?

1. Fractions that have different signs:

  • Any positive fraction is larger than any negative fraction:
  • ie: 4/25 > - 19/2

2. A proper and an improper fraction:

  • Any positive improper fraction is larger than any positive proper fraction:
  • ie: 44/25 > 1 > 19/200
  • Any negative improper fraction is smaller than any negative proper fraction:
  • ie: - 44/25 < -1 < - 19/200

3. Fractions that have both like numerators and denominators:

  • The fractions are equal:
  • ie: 89/50 = 89/50

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

  • Positive fractions: compare the numerators, the larger fraction is the one with the larger numerator:
  • ie: 24/25 > 19/25
  • Negative fractions: compare the numerators, the larger fraction is the one with the smaller numerator:
  • ie: - 19/25 < - 17/25

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

  • Positive fractions: compare the denominators, the larger fraction is the one with the smaller denominator:
  • ie: 24/25 > 24/26
  • Negative fractions: compare the denominators, the larger fraction is the one with the larger denominator:
  • ie: - 17/25 < - 17/29

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