Compare: - 72/8 and - 79/12
To compare and sort multiple fractions, they should either have the same denominator or the same numerator.
The operation of comparing fractions:
- 72/8 and - 79/12
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.
- 72/8 = - (23 × 32)/23 = - ((23 × 32) ÷ 23)/(23 ÷ 23) = - 9/1 = - 9
- 79/12 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
79 is a prime number.
12 = 22 × 3
To compare and sort the fractions, make their denominators the same.
Expand the fraction that has 1 as a denominator.
Multiply the numerator and denominator by the same number:
- 9 = - (12 × 9)/(12 × 1) = - 108/12
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.
