Multiple fractions 16/32, 12/31, 13/35, 26/39 compared and then sorted in ascending order
To compare and sort multiple fractions, they should either have the same denominator or the same numerator.
The operation of sorting fractions in ascending order:
16/32, 12/31, 13/35, 26/39
Analyze the fractions to be compared and ordered, by category:
positive proper fractions: 16/32, 12/31, 13/35, 26/39
Simplify the operation
Reduce (simplify) the fractions to their lowest terms equivalents:
To reduce a fraction to the lowest terms equivalent: divide both the numerator and denominator by their greatest common factor, GCF.
16/32 = 24/25 = (24 ÷ 24)/(25 ÷ 24) = 1/2
12/31 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
12 = 22 × 3
31 is a prime number.
13/35 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
13 is a prime number.
35 = 5 × 7
26/39 = (2 × 13)/(3 × 13) = ((2 × 13) ÷ 13)/((3 × 13) ÷ 13) = 2/3
To compare and sort the fractions, make their numerators the same.
To make the fractions' numerators the same - we have to:
1) calculate their common numerator
2) then calculate the expanding number of each fraction
3) expand 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.
To calculate the LCM, we need the prime factorization of the numerators:
12 = 22 × 3
13 is a prime number.
2 is a prime number.
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).
LCM (12, 13, 2) = 22 × 3 × 13 = 156
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
1/2 : 156 ÷ 1 = (22 × 3 × 13) ÷ 1 = 156
12/31 : 156 ÷ 12 = (22 × 3 × 13) ÷ (22 × 3) = 13
13/35 : 156 ÷ 13 = (22 × 3 × 13) ÷ 13 = 12
2/3 : 156 ÷ 2 = (22 × 3 × 13) ÷ 2 = 78
Make the fractions' numerators the same:
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:
1/2 = (156 × 1)/(156 × 2) = 156/312
12/31 = (13 × 12)/(13 × 31) = 156/403
13/35 = (12 × 13)/(12 × 35) = 156/420
2/3 = (78 × 2)/(78 × 3) = 156/234
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 final answer:
The fractions sorted in ascending order:
156/420 < 156/403 < 156/312 < 156/234
The initial fractions sorted in ascending order:
13/35 < 12/31 < 16/32 < 26/39
How are the numbers written: comma ',' used as a thousands separator; point '.' as a decimal separator; numbers rounded off to max. 12 decimals (if the case). Used symbols: '/' the fraction bar; ÷ dividing; × multiplying; + plus (adding); - minus (subtracting); = equal; ≈ approximately equal.
