Reduce (simplify) the fractions to their lowest terms equivalents:
To fully reduce a fraction, to the lowest terms equivalent: divide the numerator and denominator by their greatest common factor, GCF.
* Why do we reduce (simplify) the fractions?
By reducing the values of the numerators and denominators of fractions, further calculations with these fractions become easier to do.
A fully reduced (simplified) fraction is one with the smallest possible numerator and denominator, one that can no longer be reduced, and it is called an irreducible fraction.

An improper fraction: the value of the numerator is larger than or equal to the value of the denominator.
A proper fraction: the value of the numerator is smaller than the value of the denominator.
Each improper fraction will be rewritten as a whole number and a proper fraction, both having the same sign: divide the numerator by the denominator and write down the quotient and the remainder of the division, as shown below.
Why do we rewrite the improper fractions?
By reducing the value of the numerator of a fraction the calculations are getting easier to perform.

The fraction: - 13,979/136
- 13,979 ÷ 136 = - 102 and the remainder = - 107 ⇒ - 13,979 = - 102 × 136 - 107
- 13,979/136 = ( - 102 × 136 - 107)/136 = ( - 102 × 136)/136 - 107/136 = - 102 - 107/136

Perform the operation of calculating the fractions.
To add or subtract fractions we need them to have equal denominators (the same common denominator).
To calculate the fractions' operation we have to:
1) find their common denominator
2) then calculate the expanding number of each fraction
3) then make their denominators the same by expanding the fractions to equivalent forms - which all have equal denominators (the same denominator)
* The common denominator is nothing else than the least common multiple (LCM) of the denominators of the fractions.
The LCM will be the common denominator of the fractions that we work with.
1) Find the common denominator
Calculate the LCM of the denominators:
The prime factorization of the denominators:
7,484 = 22 × 1,871
136 = 23 × 17
6,049 = 23 × 263
8 = 23
13,199 = 67 × 197
16 = 24
7,197 = 3 × 2,399
18 = 2 × 32
26 = 2 × 13
137 is a prime number
85 = 5 × 17
167 is a prime number
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).

Rewrite the intermediate result
As a negative improper fraction:
(the numerator >= the denominator)
An improper fraction: the value of the numerator is larger than or equal to the value of the denominator.
- 45 - 4,979,921,578,317,551/4,860,160,132,935,301 =

As a mixed number (also called a mixed fraction):
A mixed number: a whole number and a proper fraction, both having the same sign.
A proper fraction: the value of the numerator is smaller than the value of the denominator.
Divide the numerator by the denominator and write down the quotient and the remainder of the division, as shown below:
- 223,687,127,560,406,096 ÷ 4,860,160,132,935,301 = - 46 and the remainder = - 1.1976144538224E+14 ⇒

- 46 1.1976144538224E+14/4,860,160,132,935,301
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
- 46 - 1.1976144538224E+14/4,860,160,132,935,301 =
- 46 - 1.1976144538224E+14 ÷ 4,860,160,132,935,301 ≈
- 46.024641460797 ≈
- 46.02
As a percentage:
A percentage value p% is equal to the fraction: p/100, for any decimal number p. So, we need to change the form of the number calculated above, to show a denominator of 100.
To do that, multiply the number by the fraction 100/100.
The value of the fraction 100/100 = 1, so by multiplying the number by this fraction the result is not changing, only the form.
- 46.024641460797 =
- 46.024641460797 × 100/100 =
( - 46.024641460797 × 100)/100 =
- 4,602.464146079687/100 ≈
- 4,602.464146079687% ≈
- 4,602.46%
