Compare and sort in ascending order the two common ordinary fractions, which one is larger: 12/60 and 21/64. Common ordinary fractions compared and sorted in ascending order, result explained below
Compare: 12/60 and 21/64
To compare and sort multiple fractions, they should either have the same denominator or the same numerator.
The operation of comparing fractions:
12/60 and 21/64
Simplify the operation
Reduce (simplify) the fractions to their lowest terms equivalents:
By reducing the values of the numerators and denominators of the fractions, further calculations with these fractions become easier to do.
To reduce a fraction to the lowest terms equivalent: divide both the numerator and denominator by their greatest common factor, GCF.
12/60 = (22 × 3)/(22 × 3 × 5) = ((22 × 3) ÷ (22 × 3))/((22 × 3 × 5) ÷ (22 × 3)) = 1/5
21/64 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
21 = 3 × 7
64 = 26
To compare and sort the fractions, make their numerators the same.
Expand the fraction that has 1 as a numerator.
Multiply the numerator and denominator by the same number:
1/5 = (21 × 1)/(21 × 5) = 21/105
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.
