Compare and sort in ascending order the two common ordinary fractions, which one is larger: 8/13 and 12/17. Common ordinary fractions compared and sorted in ascending order, result explained below
Compare: 8/13 and 12/17
To compare and sort multiple fractions, they should either have the same denominator or the same numerator.
The operation of comparing fractions: 8/13 and 12/17
Simplify the operation Reduce (simplify) the fractions to their lowest terms equivalents:
8/13 is already reduced to the lowest terms. The numerator and denominator have no common prime factors: 8 = 23 13 is a prime number.
12/17 is already reduced to the lowest terms. The numerator and denominator have no common prime factors: 12 = 22 × 3 17 is a prime number.
To compare and sort the fractions, build them up to the same numerator.
To build the fractions up to the same numerator we have to:
1) calculate their common numerator
2) then calculate the expanding number of each fraction
3) then build up their numerators the same by expanding the fractions to equivalent forms, which all have equal numerators
Calculate the common numerator
The common numerator is nothing else than the least common multiple (LCM) of the numerators of the fractions.
The LCM will be the common numerator of the compared fractions.
To calculate the LCM, we need the prime factorization of the numerators:
8 = 23
12 = 22 × 3
Multiply all the unique prime factors: if there are repeating prime factors we only take them once, and only the ones having the highest exponent (the highest powers).
Build up the fractions to the same common numerator:
Expand each fraction: multiply both its numerator and denominator by its corresponding expanding number, calculated at the step 2, above.
This way all the fractions will have the same numerator:
8/13 = (3 × 8)/(3 × 13) = 24/39
12/17 = (2 × 12)/(2 × 17) = 24/34
The fractions have the same numerator, compare their denominators.
The larger the denominator the smaller the positive fraction.
The larger the denominator the larger the negative fraction.
::: The operation of comparing fractions ::: The final answer:
The fractions sorted in ascending order: 24/39 < 24/34
The initial fractions sorted in ascending order: 8/13 < 12/17
