positive proper fractions: 112/167, 145/199, 90/159
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.
112/167 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
112 = 24 × 7
167 is a prime number.
145/199 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
145 = 5 × 29
199 is a prime number.
90/159 = (2 × 32 × 5)/(3 × 53) = ((2 × 32 × 5) ÷ 3)/((3 × 53) ÷ 3) = 30/53
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:
112 = 24 × 7
145 = 5 × 29
30 = 2 × 3 × 5
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 (112, 145, 30) = 24 × 3 × 5 × 7 × 29 = 48,720
Calculate the expanding number of each fraction:
Divide the LCM by the numerator of each fraction.
112/167 : 48,720 ÷ 112 = (24 × 3 × 5 × 7 × 29) ÷ (24 × 7) = 435
145/199 : 48,720 ÷ 145 = (24 × 3 × 5 × 7 × 29) ÷ (5 × 29) = 336
30/53 : 48,720 ÷ 30 = (24 × 3 × 5 × 7 × 29) ÷ (2 × 3 × 5) = 1,624
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:
112/167 = (435 × 112)/(435 × 167) = 48,720/72,645
145/199 = (336 × 145)/(336 × 199) = 48,720/66,864
30/53 = (1,624 × 30)/(1,624 × 53) = 48,720/86,072
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.
