Compare and sort in ascending order the two common ordinary fractions, which one is larger: 25/30 and 82/100. Common ordinary fractions compared and sorted in ascending order, result explained below
Compare: 25/30 and 82/100
To compare and sort multiple fractions, they should either have the same denominator or the same numerator.
The operation of comparing fractions: 25/30 and 82/100
Simplify the operation Reduce (simplify) the fractions to their lowest terms equivalents:
To compare and sort the fractions, build them up to the same denominator.
To build the fractions up to the same denominator we have to:
1) calculate their common denominator
2) then calculate the expanding number of each fraction
3) then build up their denominators the same by expanding the fractions to equivalent forms, which all have equal denominators
Calculate the common denominator
The common denominator is nothing else than the least common multiple (LCM) of the denominators of the fractions.
The LCM will be the common denominator of the compared fractions.
To calculate the LCM, we need the prime factorization of the denominators:
6 = 2 × 3
50 = 2 × 52
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).
Divide the LCM by the denominator of each fraction.
5/6 : 150 ÷ 6 = (2 × 3 × 52) ÷ (2 × 3) = 25
41/50 : 150 ÷ 50 = (2 × 3 × 52) ÷ (2 × 52) = 3
Build up the fractions to the same common denominator:
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 denominator:
5/6 = (25 × 5)/(25 × 6) = 125/150
41/50 = (3 × 41)/(3 × 50) = 123/150
The fractions have the same denominator, compare their numerators.
The larger the numerator the larger the positive fraction.
The larger the numerator the smaller the negative fraction.
::: The operation of comparing fractions ::: The final answer:
The fractions sorted in ascending order: 123/150 < 125/150
The initial fractions sorted in ascending order: 82/100 < 25/30
