Question

the sum of the two rational numbers is 7/9 if one of the numbers is 2/3 find the other.​

Answer 1

Answer:

1/9

Step-by-step explanation:

to find the other no. let it be x.

therefore, let x+2/3=7/9

(now change sides for solving) x=7/9-2/3

                                                          lcm=9

                                                          =7-6/9

                                                     ( answer)=1/9.

Answer 2

$\sf{\huge{\underline{\green{Given :-}}}}$

• The sum of the two rational numbers is 7/9.

• One of the numbers is 2/3

$\sf{\huge{\underline{\green{To\:Find :-}}}}$

• The other number involved here.

$\sf{\huge{\underline{\green{Answer :-}}}}$

Let the other number be x,

& the numbers is 2/3 .

According to the question,

The sum of the two rational numbers is 7/9.

x + 2/3 = 7/9

➝ x = 7/9 - 2/3

➝ x = 7 - 6 / 9

➝ x = 1 / 9

Verification :-

x + 2/3 = 7/9

x = 1 / 9

➝ 1/9 + 2/3 = 7/9

➝ 1/9 + 6/9 = 7/9

➝ 7/9 = 7/9
