Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
247,916,666,700/349,999,999,992
- The integer number above the bar is called numerator: 247,916,666,700
- The integer number below the bar is called denominator: 349,999,999,992
- The fraction bar means that the numerator is divided by the denominator.
- To get the fraction's value divide the numerator by the denominator:
The value = 247,916,666,700 ÷ 349,999,999,992
To reduce a fraction to the lowest terms equivalent: divide the numerator and denominator by their greatest common factor, GCF
To calculate the greatest common factor, GCF:
- 1. Factor the numerator and the denominator (into prime factors), build their prime factorizations.
- 2. Multiply all their common prime factors, taken by the lowest exponents.
1. Factor the numerator and the denominator:
To factor a number (into prime factors) - or, in other words, to break it down to prime factors - or, in other words, to build its prime factorization: find the prime numbers that multiply together to get that number.
The prime factorizations:
Written with exponents:
247,916,666,700 = 2 × 2 × 3 × 3 × 5 × 5 × 311 × 885,733 = 22 × 32 × 52 × 311 × 885,733
247,916,666,700 is a composite number.
Written with exponents:
349,999,999,992 = 2 × 2 × 2 × 3 × 3 × 23 × 211,352,657 = 23 × 32 × 23 × 211,352,657
349,999,999,992 is a composite number.
- Exponential notation. 23 is the writing in exponential notation of the repeating multiplication: 2 × 2 × 2. Also: 23 is called the power. 2 is the base. 3 is the exponent. 8 is the value of the power: 23 = 8.
- Prime number: a positive integer that is dividing evenly (without a remainder) only by itself and 1. A prime number has only two factors. Composite number: a positive integer that has at least one factor (divisor) other than 1 and itself.
2. Multiply all the common prime factors:
- Multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponent (the lowest powers).
GCF (22 × 32 × 52 × 311 × 885,733; 23 × 32 × 23 × 211,352,657) = 22 × 32 = 36
Reduce (simplify) the common ordinary fraction: 247,916,666,700/349,999,999,992
Divide the numerator and the denominator by their GCF.
247,916,666,700/349,999,999,992 =
(247,916,666,700 ÷ 36) / (349,999,999,992 ÷ 36) =
6,886,574,075/9,722,222,222
Yet another method to reduce the fraction
To reduce a fraction without calculating the GCF: factor its numerator and denominator, then all the common prime factors are easily identified and crossed out.
247,916,666,700/349,999,999,992 =
(22 × 32 × 52 × 311 × 885,733)/(23 × 32 × 23 × 211,352,657) =
((22 × 32 × 52 × 311 × 885,733) ÷ (22 × 32)) / ((23 × 32 × 23 × 211,352,657) ÷ (22 × 32)) =
(52 × 311 × 885,733)/(2 × 23 × 211,352,657) =
6,886,574,075/9,722,222,222
- The fraction is now reduced to the lowest terms equivalent.
- The fraction is called irreducible and it has the smallest possible numerator and denominator.
- By reducing the values of the numerator and of the denominator of a fraction the calculations with that fraction are becoming easier to do.
The fraction 6,886,574,075/9,722,222,222 is a positive proper fraction (the numerator < the denominator).
Rewrite the fraction
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
6,886,574,075/9,722,222,222 =
6,886,574,075 ÷ 9,722,222,222 =
0.708333333445 ≈
0.71
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.
0.708333333445 =
0.708333333445 × 100/100 =
70.833333344476/100 =
70.833333344476% ≈
70.83%
- In other words:
- (1) Calculate the fraction's value, (2) multiply that number by 100, and (3) add the percent sign % to it.
