Given :

• Rational number = -30/ 165

To find :

• -30/165 in standard form

Steps :

• Here, we have to find the HCF of the rational number and divide them to find the standard form.

Solution :

⇒ Let's find the HCF of 30 and 165.

• The factors of 30 = 1, 2,3,5,6,10,15,30.
• The factors of 165 = 1,3,5,11,15,33,55,165.
