How to completely reduce (simplify) the fraction 2/1 to the lowest terms (its simplest form, the smallest possible numerator and denominator)? Write the result as an improper fraction, as an integer, and as a percentage
Reduce (simplify) the fraction: 2/1
Detailed calculations below:
Fractions, brief introduction
A fraction consists of two numbers and the fraction bar: 2/1
The number above the fraction bar is the numerator: 2
The number under the fraction bar is the denominator: 1
The fraction bar means that the two numbers divide themselves:
2/1 = 2 ÷ 1
Divide the numerator by the denominator to get the value of the fraction:
The value = 2 ÷ 1
Percentages, short introduction
'Percent, p%' means 'p out of one hundred':
p% = 'p out of one hundred',
p% = p/100 = p ÷ 100
Note:
The fraction 100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value will not change.
The fraction cannot be further reduced (simplified).
It is already completely reduced (simplified) to its lowest terms (it has the smallest possible numerator and denominator).
The fraction 2/1 is an improper fraction (the denominator = 1).
An improper fraction - the numerator is greater than or equal to the denominator.
Rewrite the fraction
As an integer:
Any fraction with a denominator equal to 1 can be written as an integer by simply removing the denominator.
2/1 = 2 ÷ 1 = 2
As a percentage:
Multiply the fraction's value by the fraction 100/100
2 =
2 × 100/100 =
200/100 =
200%
In other words:
1) Calculate the value of the fraction.
2) Multiply this number by 100.
3) Add the percent sign, %.

Tutoring: simplifying fractions - reducing them to the lowest terms
Steps to simplify a fraction, to reduce it to its lowest terms:
- A fraction fully simplified, a fraction reduced to its lowest terms is a fraction that can no longer be simplified, it has been reduced to its simplest equivalent fraction, the one having the smallest numerator and denominator possible - prime to each other.
- 1) Run the prime factorization of both the numerator and the denominator of the fraction.
- 2) Calculate the greatest common factor, GCF (or the greatest common divisor, GCD) of the fraction's numerator and denominator.
- 3) Divide both the numerator and the denominator of the fraction by their greatest common factor, GCF (GCD).
- The fraction thus obtained is called a reduced fraction or a fraction simplified to its lowest terms.
- A fraction reduced to its lowest terms may no longer be reduced and it is called an irreducible fraction.
Example: reduce the fraction 315/1,155 as much as possible, simplify it to the lowest terms.
1) Run the prime factorization of both the numerator and the denominator of the fraction.
- The numerator of the fraction is 315, its breaking down into prime factors is:
315 = 3 × 3 × 5 × 7 = 32 × 5 × 7 - The denominator of the fraction is 1,155, its breaking down into prime factors is:
1,155 = 3 × 5 × 7 × 11. 2) Calculate the greatest common factor, GCF (or the greatest common divisor, GCD) of the fraction's numerator and denominator.
- The greatest common factor, gcf (315; 1,155), is calculated by multiplying all the common prime factors of the numerator and the denominator, taken by their lowest powers (their lowest exponents):
- GCF (315; 1,155) = (32 × 5 × 7; 3 × 5 × 7 × 11) = 3 × 5 × 7 = 105
3) Divide both the numerator and the denominator of the fraction by their greatest common factor, GCF (GCD).
- The numerator and denominator of the fraction are divided by their greatest common factor, GCF:
315/1,155 =
(32 × 5 × 7)/(3 × 5 × 7 × 11) =
((32 × 5 × 7) ÷ (3 × 5 × 7)) / ((3 × 5 × 7 × 11) ÷ (3 × 5 × 7)) =
3/11 - The fraction thus obtained is called a fraction reduced to the lowest terms.
Why reducing (simplifying) fractions to lower terms?
- When running operations with fractions we are often required to bring them to the same denominator, for example when adding, subtracting or comparing.
- Sometimes both the numerators and the denominators of those fractions are large numbers and doing calculations with such numbers could be difficult.
- By reducing (simplifying) a fraction, both its numerator and denominator are reduced to smaller values, much easier to work with, which will decrease the overall effort of working with that fraction.
