Compare and sort in ascending order the two ordinary fractions, which one is larger: - 71/83 and - 75/90. Ordinary fractions compared and sorted in ascending order, result explained below

Compare: - 71/83 and - 75/90

The operation of comparing fractions:
- 71/83 and - 75/90

Reduce (simplify) fractions to their lowest terms equivalents:

- 71/83 already reduced to the lowest terms;
the numerator and denominator have no common prime factors:
71 is a prime number;
83 is a prime number;


- 75/90 = - (3 × 52)/(2 × 32 × 5) = - ((3 × 52) ÷ (3 × 5))/((2 × 32 × 5) ÷ (3 × 5)) = - 5/6

To sort fractions, build them up to the same numerator.

Calculate LCM, the least common multiple of the fractions' numerators

LCM will be the common numerator of the compared fractions.

The prime factorization of the numerators:


71 is a prime number


5 is a prime number


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


LCM (71, 5) = 5 × 71 = 355

Calculate LCM, the least common multiple, online calculator


Calculate the expanding number of each fraction

Divide LCM by the numerator of each fraction:


For fraction: - 71/83 is 355 ÷ 71 = (5 × 71) ÷ 71 = 5


For fraction: - 5/6 is 355 ÷ 5 = (5 × 71) ÷ 5 = 71



Expand the fractions

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

- 71/83 = - (5 × 71)/(5 × 83) = - 355/415


- 5/6 = - (71 × 5)/(71 × 6) = - 355/426



The fractions have the same numerator, compare their denominators.

The larger the denominator the larger the negative fraction.

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).
