Question

the product of two rotional number is -8/9 if one of the number is 2/3 find the other number​

Answer 1

Step-by-step explanation:

product of two rational number:-. -8/9

one of them:-. 2/3

to find:-. other number

let's other number:-. x

2/3. x X. =-8/9

X=. -8/9 ÷3/2

and=. -4/3

Answer 2

Given:

• Product of two rational numbers = -8/9
• One of the rational number = 2/3

To find:

• The other rational number?

Solution:

Let the other rational number be x.

And,

• Product of two rational numbers is 2/3x.

⠀⠀━━━━━━━━━━━━━━━━━━━⠀

« Now, Forming an equation,

→ 2/3x = -8/9

→ x = (-8/9)/(2/3)

→ x = -8/9 × 3/2

→ x = -4/3 × 1/1

→ x = -4/3

∴ Hence, The other rational number is -4/3.

★ More to know:

★ Rational numbers: The numbers which can be written in p/q form. where q ≠ 0 i.e., q is not equal to zero.

Example - 7/8, 9/8, 567/738.

★ Irrational numbers: Irrational numbers are the totally opposite to rational numbers. They cannot be expressed in the form of p/q.

Example – e and π.
