Answer 2

Given :

• 14/27
• 49/91
• 13/52
• 27/105

To find :

• which of the following rational number is in the standard form?

Solution :

⇒ Let's find which rational numbers are in standard form.

➵ Here, we are going to find the answer by finding the least common factor of the following rational numbers.

a) 14/27 :

→ The greatest common factors of 14 and 27 are 1.

• Therefore, it is already in standard form.

b) 49/91 :

→ The greatest common factors of 49 and 91 are 7.

• Therefore, it is not in standard form.

c) 13/52 :

→ The greatest common factors of 13 and 52 are 13.

• Therefore, it is not in standard form.

d) 27/105 :

→ The greatest common factors of 27 and 105 are 3.

• Therefore, it is not in standard form.
