Question

the product of two rational number is minus 8 by 9 if one of the number is minus 4 find the other​

Answer 1

Answer:

the other number will be 2/9

Step-by-step explanation:

given that,

the product of two rational number is minus 8 by 9

given one of them = -4

let the other be x

given product = -8/9

so,

According to the question,

-4 × x = -8/9

by solving this we will get

x = -8/9 × -¼

x = 2/9

so,

the other number will be 2/9

______________________

VERIFICATION :

Now,

one of the number = -4

another number = 2/9

given product = -8/9

LHS = -4 × 2/9

RHS = -8/9

so,

-4 × 2/9 = -8/9

-8/9 = -8/9

so,

LHS = RHS

hence verified

Answer 2

Step-by-step explanation:

ANSWER :-

GIVEN THAT,RHE PRODUCT OF TWO RATIONAL NUMBER IS -8 by 9.

GIVEN ONE OF THEM = -4

LET BE THE SECOND NUMBER =X

THE PRODUCT OF (-4) AND X= -8/9

A.T.Q

-4 × x= -8/9

x= -8/9×-¼

x= 2/9
