14/3 × 6/7 = ?
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.
* By reducing the values of the numerators and the denominators of the fractions the calculations are easier to make.
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.
* In order to easily reduce a fraction, factor its numerator and denominator. This way all the common prime factors are easily identified and crossed out, without calculating the GCF.
14/3 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors.
Their prime factorization:
14 = 2 × 7
3 is a prime number (it cannot be factored into other prime factors)
6/7 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors.
Their prime factorization:
6 = 2 × 3
7 is a prime number (it cannot be factored into other prime factors)
Perform the operation of calculating the fractions
Multiply the fractions:
1) Multiply the numerators, that is, all the numbers above the fractions bars, separately.
2) Multiply the denominators, that is, all the numbers below the fractions bars, separately.
* Factor all the numerators and all the denominators in order to easily reduce (simplify) the end fraction.
14/3 × 6/7 =
(14 × 6) / (3 × 7) =
(2 × 7 × 2 × 3) / (3 × 7) =
(22 × 3 × 7) / (3 × 7)
Fully reduce (simplify) the end fraction to its lowest terms equivalent:
Calculate the greatest common factor, GCF,
of the numerator and denominator of the fraction:
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.
To fully reduce a fraction, to the lowest terms equivalent: divide the numerator and denominator by their greatest common factor, GCF.
* To calculate the GCF, we need to factor the numerator and the denominator of the fraction into prime factors.
Then 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 × 3 × 7; 3 × 7) = 3 × 7
Divide the numerator and the denominator by their GCF:
(22 × 3 × 7) / (3 × 7) =
((22 × 3 × 7) ÷ (3 × 7)) / ((3 × 7) ÷ (3 × 7)) =
(22 × 3 ÷ 3 × 7 ÷ 7)/(3 ÷ 3 × 7 ÷ 7) =
(22 × 1 × 1)/(1 × 1) =
22/1 =
4
Rewrite the intermediate result
As a positive improper fraction:
(the denominator = 1)
An improper fraction: the value of the numerator is larger than or equal to the value of the denominator.
4 = 4/1
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.
4 =
4 × 100/100 =
(4 × 100)/100 =
400/100 =
400%
The final answer:
written in three ways
As a positive integer number:
14/3 × 6/7 = 4
As a positive improper fraction:
(the denominator = 1)
14/3 × 6/7 = 4/1
As a percentage:
14/3 × 6/7 = 400%
