Simplify the operation
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.

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:

334 = 2 × 167
307 is a prime number
295,219 is a prime number
87,801 = 3 × 7 × 37 × 113
17 is a prime number
322 = 2 × 7 × 23
340 = 22 × 5 × 17
325,235 = 5 × 29 × 2,243
349,268 = 22 × 87,317
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).

134,677,159,483,963,408 ÷ 6,710,295,270,802,214 = 20 and the remainder = 4.7125406791912E+14 ⇒
134,677,159,483,963,408 = 20 × 6,710,295,270,802,214 + 4.7125406791912E+14 ⇒
134,677,159,483,963,408/6,710,295,270,802,214 =
(20 × 6,710,295,270,802,214 + 4.7125406791912E+14)/6,710,295,270,802,214 =
(20 × 6,710,295,270,802,214)/6,710,295,270,802,214 + 4.7125406791912E+14/6,710,295,270,802,214 =
20 + 4.7125406791912E+14/6,710,295,270,802,214 =
20 4.7125406791912E+14/6,710,295,270,802,214
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
20 + 4.7125406791912E+14/6,710,295,270,802,214 =
20 + 4.7125406791912E+14 ÷ 6,710,295,270,802,214 ≈
20.07022851438 ≈
20.07
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.
20.07022851438 =
20.07022851438 × 100/100 =
(20.07022851438 × 100)/100 =
2,007.022851437993/100 ≈
2,007.022851437993% ≈
2,007.02%
