The operation of comparing fractions:
- 23/143 and - 29/145
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.
- 23/143 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
23 is a prime number.
143 = 11 × 13
- 29/145 = - 29/(5 × 29) = - (29 ÷ 29)/((5 × 29) ÷ 29) = - 1/5
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 = - (23 × 1)/(23 × 5) = - 23/115
The fractions have the same numerator, compare their denominators.
The larger the denominator the larger the negative fraction.
The larger the denominator the smaller the positive fraction.
