3.3/-4
4.-2/-8​

Answer 1

Answer:

1.4/5

2.-2/15

3.-3/4

4.1/4

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 following rational numbers in standard form.
• For finding the Standard form, we have to divide the rational number -with the HCF.

Given :

• 32/40
• -8/60
• 3/-4
• -2/-8

To find :

• the standard form

Solution :

(1) 32/40 :

⇒ Let's find the HCF.

HCF of 32 and 40 = 8

⇒ Let's divide them now.

= 32 ÷ 8/40 ÷ 8

= 4/5

(2) -8/60

⇒ Let's find the HCF.

HCF of -8 & 60 = 4

⇒ Let's divide them now.

= -8 ÷ 4/60 ÷ 4

= -2/15

(3) 3/-4

⇒ Let's find the Standard form.

= 3/-4

= -3/4

(4) -2/-8

⇒ Let's find the HCF.

HCF of -2 and -8 = 2

⇒ Let's divide them now.

= -2 ÷ 2/8 ÷ 2

= -1/-4
