Question

what is meaning of standard from of fraction.
3/7 , 20/24 , 11/12 , 7/11

Answer 1

Answer :

we know : When numerator and denominator are co-prime, then the fraction is said to be in standard form , And two numbers are co-prime if they have no common factor other than 1.
So , we make factors of numerator and denominator of $\frac{3}{7}$ , As :

$\Rightarrow \frac{3\times 1}{7\times 1}=\frac{3}{7}$ So $\frac{3}{7}$ is a standard form of fraction .

And

we make factors of numerator and denominator of $\frac{20}{24}$ , As :

$\Rightarrow \frac{2\times 2\times 5}{2\times 2\times 2\times 3}=\frac{5}{2\times 3}=\frac{5}{6}$ So $\frac{5}{6}$ is a standard form of fraction .

And

we make factors of numerator and denominator of $\frac{11}{12}$ , As :

$\Rightarrow \frac{11\times 1}{2\times 2\times 3}=\frac{11}{12}$ So $\frac{11}{12}$ is a standard form of fraction .

And

we make factors of numerator and denominator of $\frac{7}{11}$ , As :

$\Rightarrow \frac{7\times 1}{11\times 1}=\frac{7}{11}$ So $\frac{7}{11}$ is a standard form of fraction .
