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.
The fraction: - 278/436
- The prime factorizations of the numerator and denominator:
- 278 = 2 × 139
- 436 = 22 × 109
- Multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponent (the lowest powers).
- GCF (278; 436) = 2
- 278/436 = - (278 ÷ 2)/(436 ÷ 2) = - 139/218
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 278/436 = - (2 × 139)/(22 × 109) = - ((2 × 139) ÷ 2)/((22 × 109) ÷ 2) = - 139/218
The fraction: - 284/450
- 284 = 22 × 71
- 450 = 2 × 32 × 52
- GCF (284; 450) = 2
- 284/450 = - (284 ÷ 2)/(450 ÷ 2) = - 142/225
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 284/450 = - (22 × 71)/(2 × 32 × 52) = - ((22 × 71) ÷ 2)/((2 × 32 × 52) ÷ 2) = - 142/225
The fraction: - 310/456
- 310 = 2 × 5 × 31
- 456 = 23 × 3 × 19
- GCF (310; 456) = 2
- 310/456 = - (310 ÷ 2)/(456 ÷ 2) = - 155/228
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 310/456 = - (2 × 5 × 31)/(23 × 3 × 19) = - ((2 × 5 × 31) ÷ 2)/((23 × 3 × 19) ÷ 2) = - 155/228
The fraction: - 297/428
- 297/428 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 297 = 33 × 11
- 428 = 22 × 107
- GCF (297; 428) = 1
To compare and sort the fractions, make their denominators the same.
To make the fractions' denominators the same - we have to:
- 1) calculate their common denominator
- 2) then calculate the expanding number of each fraction
- 3) expand the fractions to equivalent forms having the same denominator
Calculate the common denominator
The common denominator is nothing else than the least common multiple (LCM) of the denominators of the fractions.
To calculate the LCM, we need the prime factorization of the denominators:
218 = 2 × 109
225 = 32 × 52
228 = 22 × 3 × 19
428 = 22 × 107
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 (218, 225, 228, 428) = 22 × 32 × 52 × 19 × 107 × 109 = 199,437,300
Calculate the expanding number of each fraction:
Divide the LCM by the denominator of each fraction.
- 139/218 ⟶ 199,437,300 ÷ 218 = (22 × 32 × 52 × 19 × 107 × 109) ÷ (2 × 109) = 914,850
- 142/225 ⟶ 199,437,300 ÷ 225 = (22 × 32 × 52 × 19 × 107 × 109) ÷ (32 × 52) = 886,388
- 155/228 ⟶ 199,437,300 ÷ 228 = (22 × 32 × 52 × 19 × 107 × 109) ÷ (22 × 3 × 19) = 874,725
- 297/428 ⟶ 199,437,300 ÷ 428 = (22 × 32 × 52 × 19 × 107 × 109) ÷ (22 × 107) = 465,975
Make the denominators of the fractions the same:
- Expand each fraction: multiply both its numerator and denominator by its corresponding expanding number, calculated above.
- This way all the fractions will have the same denominator:
- 139/218 = - (914,850 × 139)/(914,850 × 218) = - 127,164,150/199,437,300
- 142/225 = - (886,388 × 142)/(886,388 × 225) = - 125,867,096/199,437,300
- 155/228 = - (874,725 × 155)/(874,725 × 228) = - 135,582,375/199,437,300
- 297/428 = - (465,975 × 297)/(465,975 × 428) = - 138,394,575/199,437,300
The fractions have the same denominator, compare their numerators.
The larger the numerator the smaller the negative fraction.
The larger the numerator the larger the positive fraction.
