Which fraction does not belong with the other three? 1/12, 2/12, 3/12 or 4/12. explain why

Step-by-step explanation:

A fraction is said to be in simplest form if .

HCF(a,b) refers to highest common factor of a and b .

For :

Factors of 2 are 1 and 2

Factors of 12 are 1,2,3,4,6,12

HCF(2,12)=2≠1

So, is not in simplest form.

For :

Factors of 3 are 1, 3

Factors of 12 are 1,2,3,4,6,12

HCF(3,12)=3≠1

So, is not in simplest form.

For

Factors of 4 are 1,2,4

Factors of 12 are 1,2,3,4,6,12

HCF(4,12)=4≠1

So, is not in simplest form.

For ,

Factor of 1 is 1

Factors of 12 are 1,2,3,4,6,12

HCF(1,12)=1

So, is in simplest form.

Therefore, among given fractions is in simplest form, hence, does not belong with the other three .
