Answer 2

Before, finding the answer. Let's find out how we can find the answer.

• In this question, we are asked to find the Standard form of the following Rational Number.
• So, to find that, we have to divide the Rational number by the HCF of both the numbers.

Note~

• We have to divide both the numerator and denominator with the HCF.

Given :

• -15/18​

To find :

• standard form

Solution :

• Let's find the HCF of 15 and 18.

Common Factors of 15 and 18 = 1, 3

• Here, the Highest Common factor is 3. So, let's find the standard form now.

$\sf \dfrac{-15}{18} = \dfrac{-15 \div 3 }{18 \div 3 }$

       $\sf = \dfrac{-15 \div 3 }{18 \div 3 }$

       $\sf = \dfrac{ - 5 }{6}$

Therefore, the standard form of -15/18 is -5/6.
